Transition-Metal-Catalyzed C-S, C-Se, and C-Te Bond Formations via Cross-Coupling and Atom-Economic Addition Reactions. Achievements and Challenges

In the present review, we discuss recent progress in the field of C-Z bond formation reactions (Z = S, Se, Te) catalyzed by transition metals. Two complementary methodologies are considered-catalytic cross-coupling reactions and catalytic addition reactions. The development of advanced catalytic systems is aimed at improved catalyst efficiency, reduced catalyst loading, better cost efficiency, environmental concerns, and higher selectivity and yields. The important rise of research efforts in sustainability and green chemistry areas is critically assessed. The paramount role of mechanistic studies in the development of a new generation of catalytic systems is addressed, and the key achievements, problems, and challenges are summarized for this field.
