Treatment of the readily available salts [Pt(dppm)2]2X (dppm = Ph2PCH2PPh2) with (i) Hg(CCR)2 or (ii) Hg(OAc)+ RCCH or (iii) Hg(CN)2 gives virtually quantitative yields of Y2Pt(µ-dppm)2 HgX2(Y = CCR or CN, R = Ph, p-tolyl, Me, or Prn, X = Cl) and with AgOAc + PhCCH, high yields of (PhCC)2Pt(µ-dppm)2AgX (X = Cl or I).
用(i)Hg(C CR)2或(ii)Hg(OAc)+ RC CH或(iii)Hg处理易于获得的盐[Pt(dppm)2 ] 2X(dppm = Ph 2 PCH 2 PPh 2)(CN)2实际上给出了定量的Y 2 Pt(µ -dppm)2 HgX 2的产率(Y = C CR或C N,R = Ph,对甲苯基,Me或Pr n,X = Cl),并且使用了AgOAc + PhC CH,高产率的(PhC C)2 Pt(µ -dppm)2 AgX(X = Cl或I)。
