A metallation reaction of the C-H bond in the methyl group of 3-methyl-4-phenylsydnone has been found to proceed on the action of n-buthyllithium. Subsequent reactions of 3-lithiomethyl-4-phenyl-sydnone thus obtained with electrophiles provide a convenient method for preparation of functionalised sydnones.

An α-lithium derivative of 3-alkyl-substituted sydnone was first synthesized by direct metallation of 3-methyl-4-phenylsydnone withn-butyllithium. The reactivity of the compound obtained was studied. Reactions of 3-lithiomethyl-4-phenylsydnone with various electrophiles can serve as a convenient method for preparation of functionalized sydnones.
