The cycloaddition of the N-methyl-2-pyridones 1a-d with phenyl(trimethylsilyl)ethyne (2) proceeds regioselectively to give silylated biphenyl derivatives 5a, 6b, 5c,d.Similarly the reactions of ethyl (trimethylsilyl)propiolate (3) and of benzoyl(trimethylsilyl)ethyne (4) with 1a-c afford the silylated ethyl benzoates 5e, 6f, 5g and the benzophenones 5h, 6i, 5j, respectively.
