Bis[bis(trimethylsiiyl)methyl]tin, SnR2, has an extensive chemistry, behaving as (i) a Lewis base, (ii) a Lewis acid, or (iii) undergoing oxidative addition (insertion reactions). The following complexes have been isolated, many as well characterised crystals. For class (i), these include (M = Cr or Mo)[M(CO)5(SnR2)], trans-[M(CO)4-(SnR2)2], [Fe2(η-C5H5)2(CO)3(SnR2)], [RhCl(PPh3)2(SnR2)], and [PtC
双[双(三甲基硅烷基)甲基]锡SnR 2具有广泛的化学性质,表现为(i)路易斯碱,(ii)路易斯酸或(iii)经历氧化加成(插入反应)。已分离出以下配合物,以及许多具有特征的晶体。对于(i)类,它们包括(M = Cr或Mo)[M(CO)5(SnR 2)],反式-[M(CO)4-(SnR 2)2 ],[Fe 2(η-C)5 H 5)2(CO)3(SnR 2)],[RhCl(PPh 3)2(SnR 2)]和[PtCl(PEt 3)(SnR 2)(SnR 2 Cl)]:对于(ii)类,易于与吡啶,4-甲基吡啶或哌啶热解离的1:1加合物,以及类(III),SNR 2(A)B(AB =氯化氢,氟化氢,将MeI,RCL,氯2,溴,O- 2,CH 2:CMeCMe:CH 2,[沫(η-C 5 H ^ 5)( CO)3 X](X = H或Me),的[Fe(η-C 5 H ^ 5)(CO)2 X](X = Cl或Me)时,[的Fe(CO)4
