Recent advances in N-heterocyclic carbene (NHC)-catalysed benzoin reactions

Beilstein Journal of Organic Chemistry, 2016
N-Heterocyclic carbenes (NHCs) have emerged as a powerful class of organocatalysts that mediate a variety of organic transformations. The Benzoin reaction constitutes one of the earliest known carbon–carbon bond-forming reactions catalysed by NHCs.
