Study on Cooperative Effect Between Metals of Heterodinuclear Organotransition Metal Complex

合成了一系列具有铂(钯)-过渡金属键的异双核配合物，并考察了它们的化学活性和催化活性。发现了含S小环的可逆有机基团转移、强化共插入以及区域和立体选择性开环脱硫。在这些结果的基础上，发展了新的催化反应，如硫烷的羰化反应和过渡金属氢化物的Markovnikov型湿法金属化反应，并对其反应机理进行了阐明。

Series of heterodinuclear complexes having a platinum(palladium)-transition metal bond have been prepared and their chemical and catalytic activities are examined. Reversible organic group transfer, enhance CO-insertion, and regio- and stereo-selective ring-opening desulfurization of S-containing small rings are discovered. On the basis of these results, new catalytic reactions such as carbonylation of thietanes and Markovnikov type hydrometallation of transition metal hydrides are developed and their mechanisms are clarified.
