Abstract: The invention concerns reaction products of polyisobutylenes having an average polymerisation degree P of 10 to 100 and a proportion E of 60 to 90 % of double bonds which can be reacted with maleic acid anhydride, E corresponding to 100 % of the calculated theoretical value if each polyisobutylene molecule has a reactive double bond of this type, with nitrogen oxides or mixtures of nitrogen oxides and oxygen. These reaction products are suitable as fuel additives, in particular for spark-ignition engines, and as lubricant additives.

Abstract: Process for the preparation of cis-2-(1H-1,2,4-triazol-1-ylmethyl)-2-(halophenyl)-3-(halophenyl)oxira ne I by epoxidation of Z-3-(1H-1,2,4-triazol-1-yl)-2-(halophenyl)-1-(halophenyl)propene II, in which halogen is in each case fluorine, chlorine or bromine, by reaction of the crude epoxidation product with one or more reducing agents, in which the reducing agent is added to the reaction mixture in a substantially higher amount than is necessary for destroying any peroxide compounds present.

Abstract: Preparation of Z-1,2-diarylallyl chlorides of the general formula I in which the radicals R and R independently of one another are hydrogen, halogen, alkyl, haloalkyl, alkoxy, haloalkoxy or a substituted aromatic radical, and n and m represent 1, 2 or 3, by dehydrating chlorohydrins of the formula II in which the radicals have the abovementioned meanings, at temperatures of up to 50 DEG C in the presence of a carboxylic anhydride and of an organic or inorganic acid, in an inert ether or carboxylate as the solvent, the reaction of these products to give azolylmethyloxiranes, and novel intermediates.

Abstract: alpha -Carbonylphosphine oxides are prepared by oxidising an alpha -hydroxyalkylphosphine oxide with an organic hydrogen peroxide or with an organic peracid in the presence of a compound of a metal of group 4 to 8 of the Periodic Table; novel alpha -hydroxybenzylphosphine oxides are also described. alpha -Carbonylphosphine oxides are used as photoinitiators for polymerisable compositions.

Abstract: N-oxo-azolyl methyl derivs. of formula (I) are new. R = -CH2R1 or -CHR2R3, R1 = -CA1B1Z1, -SiA3B3Me or cpd. of formula (i); R2 = -X1A4; R3 = Z2-tert.butyl; A1, A3, B1 and B3 = each 1-8C alkyl, phenylethyl or Ph, each gp. opt. mono-, di- or tri-substd. by halogen, 1-4C alkyl or 1-4C haloalkyl; A2 and B2 = each H, 1-8C alkyl or Ph; each gp. opt. mono- di- or tri-substd. by halogen, 1-4C alkyl or 1-4C haloalkyl; A4 = Ph opt. substd. by halogen; Z1 = H or OH; Z2 = CO or CHOH; X = CH or N; and X1 = O, S or CH2. USE/ADVANTAGE - (I) are fungicides and plant growth regulators. (I) have a broad spectrum of activity against phyto pathogenic fungi esp. Ascomycetes and Basidiomycetes. They are partially systemic and can be used as leaf and soil fungicides. (I) are effective against e.g. Erisiphe gramines in cereals, Verturia inaequatis on apples, Botrytis unerea on strawberries and vines, Pyricularia oryzae on rice etc. (I) also influence practically all stages of plant development.

Abstract: The application relates to a process for the preparation of alkenyl aromatics of the formula in which R can denote straight-chain or branched alkyl radicals having 1 to 12 carbon atoms or cycloalkyl radicals having 5 to 8 carbon atoms or aryl radicals, in which R and R are identical or different and can denote hydrogen or radicals as mentioned under R , and in which R represents hydrogen, hydrocarbon radicals as in R , alkenyl radicals having 2 to 12 carbon atoms, alkoxy radicals having 1 to 12 carbon atoms, aryloxy radicals having 6 to 12 carbon atoms, the formyl radical, acyl radicals having 2 to 12 carbon atoms, acetal radicals having 3 to 12 carbon atoms, ester radicals having 2 to 12 carbon atoms, the cyano radical, halogen or a haloalkyl radical having 1 to 5 carbon atoms, for example -CF3, -CCl3, -CH2CF3, in which process alcohols are split off from alkoxyalkyl aromatics of the formula (II) in which R to R have the abovementioned meaning and R represents straight-chain or branched alkyl radicals, in the presence of acidic heterogenous catalysts. The acidic heterogenous catalysts used are preferably phosphates.
