Methylene compounds are preferably prepared by reducing an aluminum halide complex of the formula STR1 in which R1 represents a C6 -C10 -aryl radical which is optionally substituted by 1 to 4 C1 -C4 -alkyl radicals, 1 to 4 fluorine, chlorine and/or bromine atoms, one C1 -C8 -alkoxy group and/or one acetoxy group, or represents a heteroaryl radical which is optionally substituted by one C1 -C4 -alkyl radical and/or one fluorine, chlorine or bromine atom and contains 5 to 10 C atoms and one O or S atom and R2 represents a C1 -C12 -alkyl radical which is optionally substituted by 1 to 5 fluorine, chlorine and/or bromine atoms, independently of R1 represents a radical as defined for R1 and, in the case where R1 =a C6 -C10 -aryl radical which is substituted by 1 to 4 fluorine, chlorine and/or bromine atoms, also represents a furyl or thienyl radical, Y represents fluorine, chlorine or bromine, with an amineborane of the formula STR2 in which R3 represents C1 -C4 -alkyl and R4 represents hydrogen or C1 -C4 -alkyl and/or with sodium borohydride and/or with potassium borohydride. 2-(2,4-Dichloro-5-fluorobenzyl)thiophene is obtainable in this way for the first time.
