1,1,1,3,3,3-Hexafluoroisopropanol (HFIP) is a polar, strongly hydrogen bond-donating solvent that has found numerous uses in organic synthesis due to its ability stabilize ionic species, transfer protons, and engage range of other intermolecular interactions. The use this exponentially increased the past decade become choice some areas, such as C–H functionalization chemistry. In review, following brief history HFIP an overview physical properties, literature examples reactions using or additive are presented, emphasizing effect each reaction.

Abstract Carbon dioxide is a harmful greenhouse gas, as well valuable resource. Here, three‐component cyclization reaction was developed for the synthesis of oxazolidine‐2,4‐diones by immobilizing CO 2 under electrochemistry and copper catalyst. Propargyl amide used substrate to capture carbon produce carboxyl anion, while selenide produced electrophilic receptor activate triple bond electrochemical conditions. Then, intramolecular carried out obtain target product. Through this environmentally friendly strategy, series important synthesized.

Abstract A catalyst‐ and oxidant‐free, highly efficient, scalable, sustainable synthetic method is developed for the selenylative annulation of 2‐alkynyl biaryls or 2‐heteroaryl‐substituted alkynyl benzenes with readily available diselenides under electrochemical conditions to synthesize a wide variety selanyl polycyclic aromatic hydrocarbons heteroaromatics in high excellent yield up 99% at room temperature short time (2‐5 h). The transformation required only electricity as green reagent produces hydrogen gas innocuous byproduct. Notably, chemistry metrics protocol are found excellent. Mechanistic studies revealed radical pathway being initiated by situ generation corresponding selenyl from conditions. Significantly, direct comparison approach that our previously iodine‐catalyzed chemical not but also more energy‐efficient, high‐yielding, sustainable, practical.

Abstract A simple and efficient visible‐light‐promoted selenylation/cyclization of enaminones have been realized for the practical synthesis 3‐selanyl‐4 H ‐chromen‐4‐ones. This reaction is performed in mild conditions, no transition metal catalyst or photocatalysts additional oxidants are required. In addition, ‐chromen‐4‐ones could be easily converted to selanyl‐functionalized pyrimidines by reacting with benzamidine substrates. magnified image
