  有机锡卤化物与锌的反应。1,2-金属间转移的发生

  摘要：

  有机锡卤化物与锌的反应通过反应性有机锡锌化合物的初步形成而进行。最终反应产物的性质取决于反应条件。在非质子溶剂中，在不存在强配位配体的情况下，四有机锡化合物是通过烷基化或芳基化反应通过中间体有机锌化合物形成的。后者是由最初的有机锡-锌反应产物中有机基团的1,2-金属间转移以及重分布和跨金属化反应产生的。在质子供体的存在下，有机锌中间体被质子化为相应的烃。强烈配位的配体阻止了1,2-移位，形成了六烷基或六芳基二锡化合物。混合的甲基苯基锡单氯化物与锌的反应中意外形成的四甲基锡似乎涉及四有机锡化合物与氯化锌之间的重新分布反应。二氯化二苯基锡和三氯化苯基锡与锌的反应再次通过最初形成的有机锡-锌化合物得到三苯基氯化锡。

  Using a laser flash photolysis/laser probe technique, we report the observation of strong absorption signals in the wavelength region 450-520 nm (highest intensity at 514.5 nm) from four potential precursors of dimethylstannylene, SnMe(2), subjected to 193 nm UV pulses. From GC analyses of the gaseous products, combined with quantum chemical excited state CIS and TD calculations, we can attribute these

  Triphenyltin-zinc compounds are easily accessible by means of hydrostannolysis reactions of zinccarbon bonds in coordinatively saturated organozinc compounds. The chemical behaviour of (triphenyltin)zinc chloride was found to depend greatly on the coordination state of the zinc atom. In the absence of strongly coordinating ligands, 1,2-intermetallic migration of a phenyl group from tin to zinc occurs

  三苯基锡锌化合物可通过配位饱和有机锌化合物中锌碳键的加氢斯坦锡水解反应轻松获得。发现（三苯基锡）氯化锌的化学行为在很大程度上取决于锌原子的配位态。在不存在强配位配体的情况下，发生苯基从锡到锌的1，2-金属间迁移。结果，其表现为苯基化试剂。强烈配位的配体N，N，N'N'-四甲基乙二胺阻止或逆转了该苯基迁移。讨论了未络合的（三苯基锡）氯化锌的可能结构。
