| Research Abstract |
We have developed new C-C bond formation methodology, which includes novel type of tellurium ate complexes as key intermediates. When the reaction of vinylic telluride with organic zinc compound was carried out, Te-Zn exchange reaction took place with retention of the geometry of vinyl moiety. The treatment of the vinylic zinc compounds with alkyl halide gave the cross coupling product. During the course of our study on the ate complex involving transition-metal complex, we have found the novel titanocene or zirconocene catalyzed alkylation and silylation of olefin and diene with the combined use of Grignard reagent. It should be noted that aliphatic alkyl halide and silyl chloride, whose usage are significantly limited in the late transition-metal catalyzed reaction were successfully employed in these catalytic reaction system.
