Chapter 12: Nucleophilic Chalcogen-containing Reagents

Nucleophilic sulfur- and selenium-containing reagents include versatile classes of compounds with broad application in organic and inorganic synthesis. In this chapter, synthetic applications of “unconventional” chalcogen nucleophilic reagents, containing chalcogen–boron, chalcogen–aluminium, chalcogen–silicon, and chalcogen–tin bonds, are reviewed. Focusing on more recent developments, reactions of these species with a variety of electrophilic partners are presented. Particular emphasis is devoted to advances in the field achieved over the last two decades.
