摘要:The present invention relates to a process for the synthesis of monohaloalkanoylferrocenes of general formula (I) in which X=Cl, Br, n is an integer such that 2 in which R1 and R2 have the abovementioned meaning, is reacted at a temperature -5 DEG C.< theta r<+15 DEG C., in the presence of AlCl3 with a halide or the anhydride of an acid of general formula (III) HOOC-(CH2)n-X, X and n having the abovementioned meaning. An acylating solution obtained by mixing AlCl2 and the acid halide or anhydride in CH2Cl2, whose temperature theta a is such that 5 DEG C.

摘要:The present invention relates to a process for the synthesis of a monohaloalkylferrocene by reaction of hydrogen with a monohaloalkanoylferrocene in the presence of PtO2 and SnCl2 as catalyst in an acetic acid medium. In this manner, a crude, particularly pure synthetic product is obtained in a high yield, simply and inexpensively. The monohaloalkylferrocenes are especially useful as surfactants or as intermediates for the synthesis of combustion catalysts for propergols. The present invention also relates to a novel monohaloalkylferrocene, namely 4-chlorobutylferrocene.
