DESIGN OF REACTION FIELD BASED ON STRUCTURAL STUDIES OF ORGANOMETALLIC REAGENTS IN SOLUTION

对溶液中二碘甲烷的结构进行了研究。它是在AXS精细结构研究和SAXS宏观结构研究的基础上进行的。结果表明，双（碘）甲烷以单体形式存在，不聚集。AXS和SAXS的结合是一种可靠的、广泛适用于溶液中多种有机金属化合物结构研究的方法。二（碘）甲烷的结构暗示了典型的刘易斯酸度，因为一个碳原子伴随着一对锌原子。1,2-二酮用双（碘）甲烷处理得到环丙烷- 1,2-二醇。2,3-环氧醇与双（碘唑）甲烷反应可引起品纳科尔型重排。

The structural studies of bis(iodozinciomethane) in solution was examined. It was performed based on the detailed fine structural studies by AXS and on the macroscopic structural studies by SAXS. It was tuned out that bis(iodozincio)methane exists as amonomeric form without aggregation. The combination of AXS and SAXS is reliable and widely applicable method for the structural studies of many types of organometallic compounds in solution.The structure of bis(iodozincio)methane implies the characteristic Lewis acidity, as a carbon accompanies a couple of zinc atoms. Treatment of 1,2-diketones with bis(iodozincio)methane gave cyclopropane- 1,2-diols. Treatment of 2,3-epoxyalcohol with bis(iodozincio)methane cause the pinacol type rearrangement.
