项目摘要

The synthetic utility of the combination of organoindium compounds and transition-metal complexes, such as nickel and palladium compounds, has been studied in order to develop new synthetic reactions and novel functional group transformations. The results obtained in this project can be summarized as follows.1.π-Allylpalladium complexes have been found to be converted readily to allylic indium reagents by the reductive transmetallation with indium(I) iodide. This reaction can be applied also for the corresponding π-allylnickel complexes, and a variety of allylic compounds including allylic alcohol themselves can be used without any activation. The allylic indium reagents prepared from π-allylpalladium and π-allylnickel complexes showed slightly different behavior. The methodology developed here provides a novel and useful environmentally benign process.2.The reactions of three-membered ring compounds, such as cyclopropenes, epoxides, and azirines, with allylic indium reagents have been systematically studied. These reactions gave a various type of products including some rearranged compounds. Their reaction mechanisms were investigated and the regio- and stereoselectivity were discussed.3.Allylic radicals have been found for the fist time to be generated easily by the photolysis of allylic indium reagents. Intramolecular cyclization reactions follow in high yields to furnish various carbocyclic and heterocyclic compounds. The reaction mechanism and the effects of the ligands on indium and the reaction solvents were investigated in detail.4.The synthetic use of gallium compounds, another member of the group 13 elements, has been investigated and their similarity in the reactivity and reaction behavior to the corresponding indium compounds has been discussed.

为了开发新的合成反应和新的官能团转化，研究了有机铟化合物与过渡金属络合物(如镍和钯化合物)的组合的合成用途。1.π-烯丙基钯配合物与碘化铟发生还原过渡反应，很容易转化为烯丙基铟试剂。该反应也适用于相应的π-烯丙基镍络合物，包括烯丙醇本身在内的各种烯丙基化合物可以在不进行任何活化的情况下使用。由π-烯丙基钯和π-烯丙基镍络合物制备的烯丙基铟试剂表现出略有不同的行为。建立的方法学提供了一种新的环境友好的方法。2.系统地研究了环丙烯、环氧化物和氮杂环等三元环化合物与烯丙基铟试剂的反应。这些反应产生了各种类型的产物，包括一些重排的化合物。研究了它们的反应机理，并讨论了它们的区域选择性和立体选择性。3.首次发现烯丙基铟试剂的光解反应容易产生烯丙基自由基。分子内的环化反应以高产率得到各种碳环和杂环化合物。详细研究了配体对铟的反应机理和反应溶剂的影响。4.研究了13族元素中的另一种成员镓化合物的合成用途，并讨论了它们与相应铟化合物在反应性和反应行为上的相似性。
