| Research Abstract |
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.
