Abstract

{The synthesis of the 16-electron iridium vinylidene complex Ir=C=CH2[N(SiMe2CH2PPh2)2] is described by starting from the cyclooctene derivative Ir(eta-2-C8H14)[N(SiMe2CH2PPh2)2] with addition of acetylene. This vinylidene complex reacts with a variety of electrophiles; thus, reaction with AlR3 (R = Me, Et) or GaMe3 leads to the formation of the new derivatives Ir(ER2)CR=CH2[N(SiMe2CH2PPh2)2] (E = Al
