摘要
Process for introducing a substituent selected from branched- or straight-chain alkyl radicals having from 1 to 12 carbon atoms, aralkyl or cycloalkyl radicals in which the alkyl moiety has from 1 to 4 carbon atoms, into a carbon chain bearing a stable functional group the said carbon chain having at least one proton in alpha -position in relation to this functional group, process whereby, in a first step, this carbon chain is reacted with a complex base comprising a mixture of alkali metal amide and alkali metal alcoholate suspended in an anhydrous organic solvent to provide temporarily a carbanion, then in a second step this carbanion is reacted in an anhydrous organic solvent with an alkyl, aralkyl or cycloalkyl halide corresponding to the substituent to be introduced.
