Abstract
This mini review is an attempt to highlight the most important contributions toward the applications of nanocatalysts in carbon–selenium cross-coupling reactions with the emphasis on the mechanistic aspects of the reactions.
Highlights
Alkynyl selenides as an important framework in organic synthesis[41,42,43,44] have been synthesized, among various methods, by reaction of alkynyl halides with nucleophilic species of selenium generated from a metal;[45] and selenodecarboxylation of arylpropiolic and cinnamic acid promoted by iodosobenzene diacetate.[46]
The results indicated that aromatic alkynes gave higher yields than aliphatic alkynes and the diorganyl diselenides reacted in the order of electron-poor aromatic diselenides > electron-rich aromatic diselenides > aliphatic diselenides
Organic selenides are of great importance in medicinal and organic chemistry, which found as skeleton units in biologically active molecules and therapeutic products, and serves as building blocks in organic synthesis, and play a prominent role as organocatalysts for asymmetric synthesis
Summary
Aryl halides are among the most commonly employed nucleophilic partners in the C–Se cross-coupling reactions.
