Effect of N-heterocyclic carbene in palladium–tin heterobimetallic catalysis: a DFT supported study on the C3–H functionalization of unprotected indoles

Abstract

A new N-heterocyclic carbene (NHC) based Pd-Sn heterobimetallic complex [(NHC)Pd(μ-Br)SnCl3]2 with a low steric crowding in the active catalytic region was designed. The reactivity of this complex was compared with...
