Abstract

Abstract : Two novel compounds based on the {Te3 Nb7 O30 } building unit were synthesized and found to be effective catalysts for the imidation and amidation reaction of anhydrides and amines to construct cyclic imides and bi-amides. Abstract : We present the synthesis and catalytic properties of two novel telluroniobates {Te15 Nb21 } and {Te10 Nb14 }. {Te15 Nb21 } is the first trimeric telluroniobate with the largest number of tellurium atoms in the Te–Nb system. Besides, both clusters exhibit excellent catalytic activity in the amidation reactions of anhydrides and amines, and cyclic imides and bi-amides can be controllably synthesized, which represents a breakthrough in the catalysis of polyoxoniobates.
