An efficient isomerization of aliphatic and cyclic olelins is achieved by using well-defined metallocene alkyne complexes as catalysts. Titanocene complexes isomerize I-alkenes to internal alkenes under mild conditions. The titanium complex was recovered quantitatively. Cyclic olcfins, e.g. cyclohex
Thezirconocene-and titanocene alkyne complexes 1-10 were tested to be effective catalysts in the dehydrocoupling of hydrosilanes like PhMeSiHz and PhJ3iHz to give oligomers and of other examples, e.g., PhSiHs polymers with cyclic oligosikmesas byproducts. @ 1997 Elsevier Science Ltd.
