摘要

An efficient and straightforward synthesis of 2H-indazoles is achieved from 2- bromobenzaldehydes, primary amines and sodium azide through consecutive condensation, C–N and N–N bond formations, catalyzed by a novel heterogeneous CuII–HT catalyst. The recoverable heterogeneous CuII–HT catalyst exhibited an impressive activity for the title reaction without any additives (expensive ligands, etc.). Heterocyclization ...
