Abstract: Transition metal carbonyls partly substituted by cyclopentadienyl radicals wherein an anhydrous transition metal salt is reacted directly with the corresponding cyclopentadienyl hydrocarbon and with carbon monoxide in an inert solvent at increased pressure and at elevated temperature, preferably in the presence of a basic compound. The invention also comprises the products of this process. The reaction of a manganous compound with a cyclopentadiene hydrocarbon and carbon monoxide in the p presence of a transition metal carbonyl and an element of Group II or Group IIIa of the Periodic Table (Derning), and the cyclopentadienyl manganese tricarbonyl compounds so produced are disclaimed (see Specification 861,371). The transition metals are those of Group Va, VIa, VIIa and VIII of the Mendeleeff Table. Specified inert solvents include dioxane, tetrahydrofuran, anisole, glycol ethers, dimethylformamide and N-methylpyrrolidone. The acid set free in the reaction may be bound by the use of pyridine, piperidine, di- or triethylamine or other secondary or tertiary amines or heterocyclic bases, or by ammonia or an alkali metal or alkaline earth metal hydroxide. It is preferred to use a metal salt of a higher valency state and to reduce it to the required valency state by a reducing agent such as iron or manganese powder, zinc dust, aluminium, magnesium chips, sodium dithionite or a formaldehyde sodium sulphoxylate addition product.

Abstract: Ferrocene compounds are prepared by reducing ferric chloride with iron in an organic solvent for the ferric and ferrous chlorides, treating with a strong base and cyclopentadiene or an alkyl cyclopentadiene, preferably in the absence of oxygen, and separating the ferrocene compound from the reaction mixture. The alkyl cyclopentadienes (specified) have alkyl groups of 1-4 C atoms and methylcyclopentadiene is preferred. The ferrous chloride which may be used in excess, e.g. up to 20 mole excess, may be reduced in acid solution, acidified using a mineral acid, e.g. HCl, H2SO4, H3PO4 or an organic acid, e.g. formic, acetic, propionic and oxalic acids which may be used in concentrations 10-6 to 1 mole per litre. The organic solvents should be such that at least 1% and preferably at least 10% by weight of the ferric and ferrous chlorides are soluble. Suitable solvents are water-miscible solvents such as primary, secondary and tertiary aliphatic alcohols, polyhydric alcohols, carboxylic acid amides, carboxylic acid nitriles and solvents having slight water solubility such as esters of lower aliphatic carboxylic acids (specified), but the preferred solvent is methanol. The strong base may be diethylamine, piperidine or an alcoholate of an alkali metal, e.g. sodium methylate, sodium ethylate and sodium n-propylate, which if an alcohol is used as the solvent, may be prepared from the same alcohol. The alcoholate may be added as a solid, a slurry or a concentrated solution. It is advantageous to stir the reaction mixture after addition of the base for 1-30 mins. The reaction may be carried out at 0-200 DEG C. and thus the reaction is complete in 0.5-8 hours. If the solvent used is miscible with water then the reaction mixture may be worked up by adding it to a dilute aqueous mineral acid from whence the ferrocene compound may be filtered off, washed with water and dried. If, however, the solvent is only slightly miscible with water it may be removed by distillation together with any volatile base present and the ferrocene compound separated from the residue by sublimation, recrystallization or steam distillation.

Abstract: Aromatic p -compounds of the formula Mea(R)x(CO)y, where Me is a group VIA, VIIA or VIII metal, a is from 1 to 4, R is a five or six membered aromatic p -system, x is from 1 to 5 and y is from 0 to 9, are used as catalysts in the refining of hydrocarbon mixtures with an oxygen-containing gas or oxygen-liberating compound which is soluble in hydrocarbons. Hydrocarbon mixtures specified are gasolines, Diesel oils, fuel oils and lubricating oils. The oxy-compound treatment may be used to effect oxidation of sulphur compounds or polymerization, condensation or resinification of nitrogen compounds, e.g. pyrrole, oxygen compounds, e.g. coumarone or indene, olefines and diolefines. The oxygen-containing gas or compound may be air or benzoyl, diacetyl, dilauroyl, dibenzoyl, di-p-toluoyl or di-t-butyl peroxide. Gasolines containing peroxides such as thermal reformates or cracking products which have stood in the air can also be used to provide the oxygen. In the catalyst Me may be manganese, nickel, iron, cobalt, molybdenum or chromium and R may be benzene, toluene, xylene, mesitylene, hexamethylbenzene, mono- or di-ethyl benzene, propylbenzene, diphenyl, polyphenyl methane or ethane, tetrahydrobenzene, anthracene, phenanthrene, pyrene, benzpyrene, coronene, cyclopentadienyl, phenyl- or mono- or di-methyl or ethyl-cyclopentadienyl or fluorene. The catalyst may be subsequently decomposed by heating or irradiation with light, e.g. from mercury vapour lamps. The refined product may be after-treated with active carbon or bleaching earths and filtration or distillation. In examples the catalysts used are dimesitylene chromium, dicyclopentadienyl nickel and cyclopentadienyl manganese tricarbonyl.ALSO:Aromatic p -compounds, MaRx(CO)y where M is a Group VIa, VIIa or VIII metal, a is 1 to 4, R is a five or six membered aromatic p system, x is 1 to 5 and y is 0 to 9 are used as catalysts in refining hydrocarbons (see Group III). M may be magnesia, nickel, iron, cobalt, molybdenum or chromium and R may be benzene; toluene; xylene; mesitylene; hexamethyl-, mono- or diethyl- or propyl-benzene; diphenyl; polyphenyl methane or ethane; tetrahydrobenzene; anthracene; phenanthrene; pyrene; benzpyrene; coronene; cyclopentadienyl; phenyl- or mono- or dimethyl- or ethylcyclopentadienyl; or fluorene. Specific compounds used in examples are dimesitylene chromium, dicylopentadienyl nickel and cyclopentadienyl manganese tricarbonyl of formulae:
