Coupling reactions of an allenylcarbene complex with alkynes and styrene

The allenylcarbene complex [OSCl2{=CPh(eta(2)-CH=C= CHPh)I(PPh3)21 undergoes coupling reactions with HC equivalent to CSiMe3 and PhC equivalent to CC equivalent to CPh to produce the fulvene complexes [OSCl2(eta(6)-C-5,H-2(Ph)(SiMe3)(=CHPh))(PPh3)] and [OSCl2(eta(6)-C5H(Ph)2(C equivalent to CPh)(=CHPh))(PPh3)], respectively. A similar coupling reaction also occurs between [OSCl2(=CPh(eta(2)-CH=C=CHPh))(PPh3)2] and styrene. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
