以二碘甲烷和锌为原料,在一定量的铅的催化作用下制备了双(碘)甲烷。该化合物作为有机合成试剂具有很高的潜力。与羰基化合物的反应产生甲基化产物。试剂还依次与几个亲电试剂反应。作为路易斯酸的功能也是独一无二的。它与1,2 -二羰基化合物以面对面的方式配位,并有助于对试剂碳中心的逐步亲核攻击;产物是顺式- 1,2 -环丙二醇。还对结构研究进行了检查。(2003年3月12日,野崎仁司m.j. A发表)
Bis(iodozincio)methane was prepared from diiodomethane and zinc in the presence of a catalytic amount of lead. The compound showed a high potential as an organic synthetic reagent. The reaction with carbonyl compounds proceeded to give methylenated products. The reagent also reacted with a couple of electrophiles sequentially. The function as Lewis acid is also unique. It coordinated with 1, 2-dicarbonyl compounds in face-to-face manner and assisted the stepwise nucleophilic attack on the carbon center of the reagent; the products are cis-1, 2-cyclopropanediols. A structural study was also examined.(Communicated by Hitosi NOZAKI, M. J. A., March 12, 2003)
