    Abstract: Mixed-alkyl lead compounds are prepared by contacting a mixture of at least two tetraalkyl lead compounds capable of redistribution with an activated aluminosilicate clay, a synthetic zeolite, a natural zeolite, an activated silica or an activated alumina. These mixed alkyl lead compounds may be used in anti-knock compositions, and the redistribution reaction may be carried out in the presence of halogenated hydrocarbon materials employed as scavengers.

    Abstract: The invention comprises substituted succinimides of the general formula wherein Ar is an aryl group. The compounds, which are fungicides, are prepared by reacting a ,a -dichlorosuccinic anhydride with an N-arylamine and effecting an inner condensation of the resulting N-aryl-a ,a -dichlorosuccinamic acid by reaction with an inorganic acid halide, e.g. thionyl chloride, the sulphur chlorides, phosphorus trichloride and pentachloride and the oxychlorides. The examples describe the preparation of compounds in which the aryl group is phenyl, p-chlorophenyl, 2,5-dichlorophenyl, p-tolyl, p-diphenyl and p-nitrophenyl; and a large number of other compounds is listed in which phenyl and other aryl groups contain hydrocarbon, halogen and nitrogen-, oxygen-and sulphur-containing substituents.ALSO:A fungicidal composition comprises a carrier and an N-aryla , a 1 - dichlorosuccinimide. Examples of such compounds are N-phenyl-, N-p-chlorophenyl-, N-2,5-dichloro-phenyl-, N-p-tolyl-, N-p-diphenyl- and p-nitrophenyl-a , a 1- dichlorosuccinimides but a large number of other compounds are listed in which phenyl and other aryl groups, particularly naphthyl, contain hydrocarbon, halogen and nitrogen-, oxygen- and sulphur-containing substituents. The composition may be in the form of a water suspension which preferably include surface-active active agents such as salts of alkyl sulphates and alkyl and aralkyl sulphonates and alkylamide sulphonates, alkylaryl polyether alcohols, polyhydric alcohol-fatty acid esters, and the ethylene oxide addition products of such esters and of long chain mercaptans. The fungicides may also be applied in solution in an organic solvent, e.g. benzene, xylene, toluene, acetone, methylethyl ketone, cyclohexanone, carbon tetrachloride, trichloro- and perchloroethylene, kerosene, ethyl, butyl and amyl acetates, ethanol, isopropanol, amyl alcohols, and the monoalkyl ethers of ethylene-and diethylene glycol. The carrier may also consist of solid diluents such as talc, cellulosic powders, and clays such as Fullers earth, diatomaceous earth, Pyrophillite, Bentonite, Montmorillonite and Attaclay. Oil-in-water emulsions may be prepared by dispersing a solution of the fungicide in a water-insoluble solvent in water containing a wetting agent. A combination of the above methods of application may also be used, e.g. mixing a wetting-agent with a dust formulation and suspending in an aqueous or other liquid medium. The compositions may also include other additives, e.g. vegetable oils, gums and other adhesives, humecants, fertilisers, herbicides and other fungicides and biocides. The fungicides may be used at concentrations of from 0.1 to 50,000 parts per million and are non-toxic to plants. Their effect on Tomato Blight is described.

    Abstract: Organo-transition metal complexes of the type: or where M = a transition metal of Group IV-VIIb and VIII of the Periodic Table; A1=O or S; A2=N or P; R1 and R2 are organic groups characterized by the absence of (1) olefinic unsaturation, (2) hydrogen atoms on the carbon atom in the a -position to the carbon atom to which the O, S, N or P is bonded; R3=an organic radical and x and y are small whole numbers dependent upon the valence of M, x being 1, 2 or 3, y being 1 or 2, are prepared by reaction of a transition metal salt with an organo metallic intermediate of the type formed by reaction of a non-transition metal with organic compounds of the type or where R1, R2, R3 and A1 and A2 have the meaning above defined. The radical R3 above may be an alkyl, aryl, alkenyl, alkaryl or aralkyl radical containing 1-16 carbon atoms. Transition Transition metal salts employed are generally ionic compounds, e.g. halides, nitrates, sulphates, oxalates or acetates and the non-transition metal may be an alkali or alkaline earth metal or aluminium. The organo metallic intermediate is preferably formed by reaction carried out in an inert atmosphere and by addition of the non-transition metal as a dispersion in mineral oil. The organo metallic intermediate thus formed may then be reacted directly with the transition metal salt. Alternatively, the organo metallic complex may be formed in one reaction by reacting the appropriate organic compound having a formula as specified above with a non-transition metal in the presence of a non-transition metal salt. The reactions may be carried out in an inert solvent, e.g. benzene, toluene or hexane or preferably in non-reactive cyclic ethers, e.g. dioxane or tetrahydrofurane. Of the organic compounds referred to above which may be ketones, thiones, imines or phosphine compounds, ketones and thiones containing 9-25 carbon atoms/molecule, e.g. 2,2,4,4 - tetramethyl 1-3-pentanethione; bis-(tert.-butyl) thione; bis-phenylthione; bis-(4-nitrohexyl) thione; bis-(1,1,3,3,4,4-hexamethyl pentyl) ketone; bis-(p-biphenyl) ketone; 1-phenyl 1-2, 5-diethyl 1-2, 4-dimethyl-1-hexathione; bis-(p-dimethyl amino phenyl) ketone; di-tert.-butyl ketone; diphenyl ketone; bis-(p - nitro - phenyl) thione, phenyl - tert. - butyl ketone; bis-(m-nitrophenyl) ketone; bis-(1-ethyl-1,3-dimethyl butyl) ketone, and imines and phosphine compounds containing 9-25 carbon atoms/molecule, e.g. p,p1-diaminobenzohydrylidene methyl imine; p,p1-diphenyl benzohydrylidine-n hexyl phosphine; m,m1-dinitro benzhoydrylidene benzyl phosphine; 4,4,6,6-tetramethyl - 5 - nonylidene ethyl imine; N - benzohydrylidene phenylimine; 2,2,4,4-tetramethyl - 3 - pentylidene methylimine; p-methyl benzohydrylidene benzylimine, benzohydrylidine - n - hexylimine and 2,4-diethyl-2,4-dimethyl-3-pentylidene-p-nitrophenylimine are specified. Use of such organo metallic complexes to prepare transition metal carbonyls by reaction with CO (see Group III) is specified.ALSO:Transition metal carbonyls are prepared by reaction of CO with organo-transition metal complexes of the type: or where M = a transition metal of the Group IVb, Vb, VIb, VIIb and VIII of the Periodic Table; A1 = O or S; A2 = N or P; R1 and R2 are organic groups characterized by the absence of (1) olefinic unsaturation, (2) hydrogen atoms on the carbon atom in the a position to the carbon atom to which the O, S, N or P is bonded; R3=an organic radical and x and y are whole numbers dependent upon the valence of M, and being 1, 2 or 3, y being 1 or 2. R3 may be an ethyl, aryl, alkenyl, alkaryl or aralkyl radical containing 1-16 carbon atoms, organic hydrocarbon radicals being preferred. Complexes of the type where A1=O and A2=N are preferred especially the complex formed by reaction of a transition metal salt and bis-(N-sodio-benzo phenoneimine). In operation, a pressure vessel containing the required complex is pressurized at ambient temperature with Co to 250-50,000 p.s.i.g., preferably 500-3000 p.s.i.g., and is slowly heated to a reaction temperature of 50-300 DEG C., preferably 150-230 DEG C., for a time of 1/2 -2\ba1/2 hours or until the system no longer absorbs Co. The reaction may be carried out in an inert solvent, e.g. benzene, toluene or hexane or preferably polar, non-reactive cyclic ethers, e.g. dioxane or tetrahydrofurane. The metal carbonyl is recovered from the reaction products by hydrolysis and steam distillation followed by extraction of the aqueous distillate with a solvent, e.g. benzene, toluene or cyclohexane and finally purified by crystallization. The organo metallic complexes (I) and (II) above may be prepared (see Group IV (b)) by reaction of a transition metal salt, e.g. halides, nitrates, sulphates, oxalates or acetates, with an organo metallic intermediate formed by the reaction of stoichiometric amounts of a non-transition metal, e.g. alkali metals, alkaline earth metals and aluminium, and organic compounds of the type i.e. a ketone (A1=O) or a thione (A1=S) or i.e. an imine (A2=N) or a phosphine compound (A2=P). The use of an imine, especially N-benzohydrylidenephenylimine, is preferred. The Specification contains numerous examples of the various ketones, thiones, imines and phosphine compounds which may be employed.
