Preparation and reactions of bis(isocyanide)(η5-indenyl)rhodium(I) complexes
Abstract
The bis(aryl isocyanide)(η5-indenyl)rhodium(I) complexes [Rh(η-C9H7)(RNC)2][1; R = 4-Br-2,6- Me2C6H2 2,6-Me2C6H3, or 2,4,6-But3C6H2] were prepared by the reactions of [Rh(RNC)3Cl] or a mixture of [{RhCl(cod)}2](cod = cyclo-octa-1,5-diene) and RNC with indenyl-lithium. Reaction of (1) with tetracyanoethylene (tcne) or methyl iodide gave an olefin complex, [Rh(η5-C9H7)-(RNC)(tcne)], or an iminoacyl complex, [Rh(η5-C9H7)(RNC){C(Me)NR}I], respectively.
