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

Abstract

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.

Cooperativity between the Silver(I) and Iodine(III) Centers in Electrophilic Activation of Organic Substrates

“…Considering this, AgOTf has been chosen as a model noble metal-containing compound, since availability of the triflate-anion excludes anion metathesis upon addition of any of Cat1 OTf -Cat4 OTf and this compound is relatively stable under mild conditions in the presence of oxygen and traces of water, as well as it has many applications in catalysis. [55][56][57][58] Iodolium salt-silver(I) interplay in the solid state. To study possible binding modes between the iodolium salts Cat1 OTf -Cat4 OTf and AgOTf, cocrystals of these species were tried to obtain from MeOH solution.…”

Pd-catalyzed site-selective C(sp2)–H chalcogenation of amino acids and peptides using a picolinamide auxiliary

“…[70][71][72][73][74][75] Therefore, the synthesis of chalcogenides has been an immense subject of study. In this regard, several metal-mediated traditional cross-coupling strategies [76][77][78][79][80][81][82][83] and metal-free protocols [84][85][86][87][88][89] have used typical approaches to assemble chalcogenides. However, most of the methods suffer from the inevitable need to perform pre-functionalization of the starting materials, limited substrate scope and harsh reaction conditions.…”

Metal-Free One-Pot Multi-Functionalization of Unsaturated Compounds with Interelement Compounds by Radical Process

“…Recently, methods using transition metal catalysts have also been reported, but these methods involve significant costs for waste disposal and the removal of metal residue in the products. Therefore, the development of more practical and atom-efficient methods is desired [ 10 , 11 , 12 ].…”
