A Late Stage Strategy for the Functionalization of Triazolium-based NHC catalysts

Synlett. 2014;25(18):2665-2668. doi: 10.1055/s-0034-1379167.

Abstract

A strategy for the diversification of triazolium-based catalysts is presented. This method is based on the reduction to the triazoline, which serves as a suitable and stable substrate for Pd-mediated cross-coupling, followed by trityl cation mediated reoxidation to the triazolium.
