亚磷酸盐和膦络合物- ptcl2 ((PX(CH2)mCHCH2)3)2(X/m= O/3, O/4, O/5, -/5, -/6)与Grubbs催化剂反应,加氢,产率- ptcl2 (P(X(CH2)2m+2X)3P)(6 - 40%)。晶体结构建立了类似降落伞的基元,其中一个X(CH2)2m+2X桥大致位于铂配位面上,其他桥位于铂配位面上或下方。
Reactions of the phosphite and phosphine complexescis-PtCl2((PX(CH2)mCHCH2)3)2(X/m= O/3, O/4, O/5, -/5, -/6) with Grubbs’ catalyst, followed by hydrogenations, yieldcis-PtCl2(P(X(CH2)2m+2X)3P) (6–40%). Crystal structures establish parachute-like motifs in which one X(CH2)2m+2X bridge lies roughly in the platinum coordination plane, and the others lie above and below.
