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.
