°C. Reaction of the methyl isocyanoacetate complex [Ru]C⋮NCH2COOMe}X (2d) with n-Bu4NOH causes hydrolysis of the ester group to give the ruthenium oxazolone complex 4d. The insertion of the CO group of acetone, aldehyde, ester, and amide into the C−C bond of the three-membered azirinyl ring of 3a−c yields a variety of five-membered oxazolinyl complexes 5−7. The regiospecificity of the insertion differs
