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.
