摘要：

An active niobium catalyst was developed via a simple and nontoxic reduction method from NbCl5/hydrosilane and utilized for the selective [2 + 2 + 2] cycloaddition reaction of terminal alkynes and alkenes/alpha,omega-dienes, to give 1,3-cyclohexadiene derivatives in high yields with excellent chemo- and regioselectivity.
