Recently, from materials science viewpoint, development of chalcogen-containing π-conjugated systems is much attractive because of their unique photochemical and electronic properties. We have studied new methods for the highly regio- and stereoselective introduction of group 16 heteroatom moieties into unsaturated bonds, i.e., photoinduced radical reactions and transition-metal-catalyzed reactions. Therefore, applications of these methods to construction of chalcogen-containing π-conjugated systems are of great importance because these approaches may lead to discover of new functional materials.
This review deals with the introduction of chalcogeno groups into acetylene derivatives bearing redox or photochemical properties such as ferrocene, porphyrin, and diethynylbenzene derivatives.
