The highly functional chromio nitrile ylides Cr(CO)5C≡N–C(Cl)–PR3 (R = Ph, NMe2) (2a, b) form readily in mixtures of Cr(CO)5CNCCl3 (1) with the respective phosphanes. Their reactions without isolation with the acylating agent Cr(CO)5CN(C=O)Ar (

The cyclization reaction of coordinated β-functional phenyl isocyanides was used to generate coordinated anellated N-heterocyclic carbenes. Coordinated 2-trimethylsiloxyphenyl isocyanide reacts, after SiO bond cleavage, to yield a complex with a coo

Tungsten complex 5 with a coordinated 2-azidoethyl isocyanide ligand reacts with PMe3 at the azido function to give a complex with a coordinated iminophosphorane which upon hydrolysis of the PN bond yields a complex with an NH,NH-stabilized N-heteroc

The reaction of 2-azidophenyl isocyanide (7) with [M(CO)(5)(thf)] (M=Cr, W) yields the isocyanide complexes [M(CO)(5)(7)] (M=Cr 8, M=W 9). Complexes 8 and 9 react with tertiary phosphines such as triphenylphosphane at the azido function of the isocya
