Group 15 Analogous of N-Heterocyclic Carbene with two π Accepting Orbitals:

A Case Study

Abstract

N-heterocyclic nitrenium cation are found to have high π accepting ability (Borpuzari MP, Guha AK, Kar R (2015) Struct Chem 26:859–871). However, the tuning of π accepting ability of this class of ligand is not extensively studied. In this report, we have explore the ligation ability of N-heterocyclic nitrenium cation with boron atom at its backbone and reported first time, the presence of two π accepting orbitals, which may open up new possibilities towards catalytic applications which require the stabilization of electron-rich metal centres.
