Treatment of gem-di(iodozincio)methane with pyridine or diamine derivatives resulted in the isolation of a storable gem-di(iodozincio)methane species. Use of the sterically bulky bipyridine ligand gave a gem-di(iodozincio)methane complex, which allowed the first X-ray structural analysis of such species. This work represents a rare example of the isolation of an organometallic reactive species in Schlenk equilibrium and thus provides new insight into the design of efficient and storable organometallic reagents. The isolated gem-di(iodozincio)methane complexes serve as effective methylene dianion synthons for olefination of carbonyl compounds.
用吡啶或二胺衍生物处理二碘二锌甲烷，可分离出一种可储存的二碘二锌甲烷物种。使用空间位阻大的联吡啶配体得到二碘二锌甲烷配合物，这使得首次对这种物种进行了 X 射线结构分析。这项工作代表了在 Schlenk 平衡中分离有机金属反应性物种的罕见实例，从而为设计高效和可储存的有机金属试剂提供了新的见解。分离得到的二碘二锌甲烷配合物可用作羰基化合物的烯烃化的有效亚甲基二阴离子合成子。
