Preparation of 1,2-Diaryl(heteroaryl)pyrroles and -3-methylpyrroles from N-Allylbenzotriazole

Abstract
Numerous 1,2-diaryl(heteroaryl)pyrroles and -3-methylpyrroles were prepared in a two-step procedure from N-allylbenzotriazoles via intramolecular oxidative cyclization in the presence of Pd(II) catalyst.
