Modern developments in aryl radical chemistry.

This review summarizes recent advances in the field of aryl radical chemistry. In particular, modern developments of the well-known Meerwein, Pschorr, and Gomberg-Bachmann reactions are presented along with new applications in natural product syntheses. Among the methods for the generation of aryl radicals, tin hydrides play a predominant role, but more and more attractive and promising alternatives are beginning to emerge.
