The first single electron transfer reductive deuteration of nitriles using D2O as a deuterium source has been developed for the synthesis of valuable α,α-dideuterio amines. A mild reductant (SmI2) was employed as the electron donor with Et3N as the additive. This reaction is amenable to both aromatic and aliphatic nitriles and features high deuterium incorporation, excellent regioselectivity, and good

Normally liquid, omega-hydrofluoroalkyl ether compounds (and selected mixtures thereof) have a saturated perfluoroaliphatic chain of carbon atoms interrupted by one or more ether oxygen atoms. The compounds can be prepare, e.g. by decarboxylation of the corresponding fluoroalkyl ether carboxylic acids and are useful, e.g., in cleaning and drying applications.
predominantly catalyze Michael addition reactions. Inorganic and organic base‐catalyzed Michael addition reactions have been reported. However, known base‐catalyzedreactions suffer from the requirement of solvents, additives, high pressure and also side‐reactions. Herein, we demonstrate a mild and environmentally friendly strategy of readily available KOtBu‐catalyzed Michael addition reactions. This simple
