Product Divergence in Coinage-Metal-Catalyzed Reactions of π-Rich Compounds

Abstract

This short review aims to summarize how the product outcome of reactions of a common starting material can sometimes be controlled by the judicious choice of copper, silver or gold as the catalyst. It highlights the different reactivities observed in the functional group transformations of π-rich substrates mediated by the three group 11 metal salts.1 Introduction2 Reactions of Propargyl Amines, Esters and Their Derivatives3 Reactions of Phenylacetylene Derivatives4 Reactions of π-Rich Alcohols and Ethers5 Indolyl Cyclopropene and Alkynone Rearrangements6 Reactions Involving Metal-Carbene and Metal-Carbenoid Intermediates7 Conclusion
