reactions of Hg(CF3)2 with Group 4 organometallic compounds MMe4(M = Si,Ge,Sn, or Pb), MMe3(CF3)(M = Sn or Pb), and M2R6(M = Si or Sn, R = Me; M = Ge, Sn, or Pb, R = Ph) have been investigated. Exchange of one CF3, group with a methyl group occurs for SnMe4, SnMe3(CF3), and PbMe4; the lead derivative reacts much more readily than the tin compound. Cleavage of the metal-metal bond with formation of MR3(CF3)
Hg(CF 3)2与4族有机金属化合物MMe 4(M = Si,Ge,Sn或Pb),MMe 3(CF 3)(M = Sn或Pb)和M 2 R 6(M = Si或Sn,R = Me; M = Ge,Sn或Pb,R = Ph)已被研究。SnMe 4,SnMe 3(CF 3)和PbMe 4发生一个CF 3基与甲基的交换。铅衍生物比锡化合物更容易反应。对于Sn 2 Me 6,已经实现了金属-金属键的裂解以及MR 3(CF 3)的形成但是对于Si 2 Me 6和六苯基衍生物却不发生。研究了PbMe 3(CF 3)与溴,氯化氢和水的反应及其热稳定性。讨论了第4组混合三氟甲基-甲基衍生物的光谱性质。
