Hydrogenations at room temperature and atmospheric pressure with mesoionic carbene-stabilized borenium catalysts

Angew Chem Int Ed Engl. 2015 Feb 16;54(8):2467-71. doi: 10.1002/anie.201409250. Epub 2015 Jan 13.

Abstract

1,2,3-Triazolylidene-based mesoionic carbene boranes have been synthesized in a convenient one-pot protocol from the corresponding 1,2,3-triazolium salts, base, and borane. Borenium ions are obtained by hydride abstraction and serve as catalysts in mild hydrogenation reactions of imines and unsaturated N-heterocycles at ambient pressure and temperature.

Keywords: Lewis acids; borenium; catalysis; hydrogenation; mesoionic carbenes.
