Abstract

Reactions Of RuCl(PPh₃)(PCP) (PCP = 2,6-(PPh₂CHa)₂C₆H₃) with PhC≡CH and HC≡CC-(OH)Ph₂ gave the unusual coupling products RuCl(PPh₃)(η⁴-PhCH=C-2,6-(PPh₂CH ₂)₂C₆H₃) and RuCl(PPh₃)(η⁴-Ph₂C(OH)CH=C-2,6-(PPh ₂CH₂)₂C₆H₃), respectively. Dehydration was observed in the coupling reactions Of RuCl(PPh₃)(PCP) with HC=CC(OH)PhMe and HC≡C-cyclo-C₆H₁₀(OH). Thus, the coupling products RuCl(PPh₃)(η⁴-CH₂=CPhCH=C-2,6-(PPh ₂-CH₂)₂C₆H₃) and RuCl(PPh₃)(η₄-cyclo-C₆H ₉-CH=C-2,6-(PPh₂CH₂)₂C ₆H₃) were obtained from the reactions of RuCl(PPh₃(PCP) with HC=CC(OH)PhMe and HC=C-cyclo-C₆H₁₀(OH), respectively. Treatment of [Ru(PMe₃)₂(PCP)]BF₄ with PhC=CH produced [Ru(PMe₃)₂(η⁴-PhCH=C-2)6-(PPh ₂CH₂)₂C₆H₃)]BF ₄.
