Abstract

Reaction of RuCl2(PPh3)3 with 1,3-(PPh2-CH2)2C6H4 in refluxing 2-propanol produced RuCl(PPh3)(PCP) (PCP = 2,6-(PPh2CH2)2C6H3). Reaction of RuCl(PPh3)(PCP) with PhC≡CH gave the unusual coupling product RuCl(PPh3){η4-CHPh=C-2,6-(PPh2CH 2)2C6H3}, which has been characterized by X-ray diffraction. Coupling also occurred between RuCl-(PPh3)(PCP) and HC≡CC(OH)(Ph)CH3 to give RuCl-(PPh3){η4-CH2=CPhCH=C-2,6-(PPh 2CH2)2C6H3}.
