Complexes (η6-arene)(PR3)RuCl21 react with HCCâCCâCPh2OX derivatives (X = H, SiMe3) to afford, in alcohol or in the presence of HNPh2, 3-alkenyl allenylidene complexes [(η6-arene)(PR3)ClRuCCC(Y)CHCPh2]+(Y = OEt 4a, OPri5a, NPh26) and diynylâruthenium derivatives in the presence of HNPri2.
配合物 (β6-芳烃)(PR3)RuCl21 与 HCC–CC–CPh2OX 衍生物 (X = H, SiMe3) 反应,在酒精中或 HNPh2 存在下生成 3-烯基亚烯基配合物 [(δ 6-芳烃)(PR3)ClRuCCC(Y)CHCPh2]+(Y = OEt 4a, OPri5a, NPh26) 和 HNPr2 存在下的二炔基钌衍生物。
