Synergistic catalysis: A powerful synthetic strategy for new reaction development

Chem. Sci., 2012, 3,633-658
DOI: 10.1039/C2SC00907B, Perspective

Anna E. Allen, David W. C. MacMillan
Synergistic catalysis, the simultaneous activation of two reacting partners by discrete catalysts to enable new or elusive chemical transformations, is a valuable synthetic strategy that is growing in popularity. This review seeks to describe the new transformations that highlight the rapid onset of this powerful multi-catalysis concept.
