Palladium catalysed coupling of imidazoles to alkynyl and vinyl substrates

Article abstract of DOI:10.1016/0040-4020(96)00823-X

Methods for preparing 4-substituted imidazoles from the palladium(0) catalysed couplings of N-protected 4-haloimidazoles with alkynes or alkynyl- and vinyltrialkyltin derivatives or from the coupling reactions of 4-trimethylstannylimidazole 9 with aryl and vinyliodides and bromides under Stille conditions is reported.
