Abstract:	Reactions of RuCl(PPh3)(PCP) (PCP = 2,6-(PPh2CH2)2C6H3) with PhCCH and HCCC(OH)Ph2 gave the unusual coupling products RuCl(PPh3)(η4-PhCHC-2,6-(PPh2CH2)2C6H3) and RuCl(PPh3)(η4-Ph2C(OH)CHC-2,6-(PPh2CH2)2C6H3), respectively. Dehydration was observed in the coupling reactions of RuCl(PPh3)(PCP) with HCCC(OH)PhMe and HCC-cyclo-C6H10(OH). Thus, the coupling products RuCl(PPh3)(η4-CH2CPhCHC-2,6-(PPh2CH2)2C6H3) and RuCl(PPh3)(η4-cyclo-C6H9-CHC-2,6-(PPh2CH2)2C6H3) were obtained from the reactions of RuCl(PPh3)(PCP) with HCCC(OH)PhMe and HCC-cyclo-C6H10(OH), respectively. Treatment of [Ru(PMe3)2(PCP)]BF4 with PhCCH produced [Ru(PMe3)2(η4-PhCHC-2,6-(PPh2CH2)2C6H3)]BF4.
