Alkylation of 4(5)-substituted 1H-imidazoles using the corresponding reagents gave imidazole 1,4-isomers containing phosphoryl and carboxyl groups together in the ring and in the alkyl fragment. The alkylation of pyrazoles containing a carboxyl group at positions 3(5) and 4 of the ring using diethyl phosphonomethyltriflate has been studied.
