摘要：

Niobium(V) chloride in a carbon tetrachloride solution catalyses the cyclotrimerization of phenylacetylene. The reaction is characterized by a well-defined induction period. During the induction period reduction of niobium(V) to catalytically active niobium(III) occurs. The reduction rate can be greatly accelerated by irradiating the system with visible light. The light effect is incorporated in a reaction scheme which makes it possible to describe the reaction course. © 1990.
