| Research Abstract |
Transition-metal-catalyzed[2+2+2] cycloaddition of unsaturated compounds has been extensively studied for the formation of various aromatic and unsaturated cyclic compounds. In this study, we reported that thermally stable low-vallent Nb(III) compounds, NbCl_3(DME) or NbCl_5/(TMS)_3SiH provide as an efficient catalysts for the multi-component coupling[2+2+2] intermolecular cycloaddition reaction of terminal alkynes, internal alkynes and alkenes leading to 1, 3-cyclohexadiene derivatives as the desired products in excellent yield and chemo/regioselectivity.
