一氧化碳氢化中间物模型的过渡金属-烯酮(亚烯酮基)络合物

Transition metal-ketene (ketenylidene) complexes as models for the expected intermediates of carbon monoxide hydrogenation

有机烯酮的化学已有80年的历史,但过渡金属-烯酮和金属-亚烯酮基络合物的研究才进行几年。由于这类络合物的化学与一碳化学的研究密切相关而引人注目,且迅速发展成为有机金属化学的一个重要分支。本文就过渡金属-烯酮和金属-亚烯酮基络合物的合成、结构、反应性能和作为一氧化碳氢化中间物模型的研究,包括作者过去的研究结果,作简要介绍。

Ketene chemistry has been investigated for over 80 years, However transition metal-ketene and metal-keteny-lidene complexes has been studied only in very recent years, Their chemistry has drawn considerable attention and has zapidly grown. to become an important branch of organometallic chemistry because of a close relation between these metal complexes and C_1-chemistry。 In this article, synthesis, structure and chemical reactivities of transition metal-ketene and-ketenyli.dene complexes and studies on these cluster complexes as models for the possible intermediates of carbon monoxide hydrogenation are briefly reviewed
