Metal-Free Synthesis of Aryl Selenocyanates and Selenaheterocycles with Elemental Selenium

This work reports a green method for the synthesis of aryl selenocyanates via a three-component reaction of arylboronic acids, Se powder, and trimethylsilyl cyanide (TMSCN) under metal-free and additive-free conditions. Remarkably, TMSCN acts as not only the substrate, but also the catalyst. Various selenaheterocycles can be also accessed with a catalytic amount of TMSCN.

An electrochemical method for deborylative seleno/thiocyanation of arylboronic acids under catalyst- And oxidant-free conditions

An electrochemical deborylative seleno/thiocyanation of arylboronic acids has been well established to synthesize the corresponding aryl seleno/thiocyanates with good functional group tolerance under ambient conditions. A gram-scale reaction has been performed to highlight the advantages of the protocol. Preliminary mechanistic studies indicate that the oxidation of the seleno/thiocyanate anion occurs prior to that of the arylboronic acid substrate in galvanostatic mode, and that free radicals are involved in the process.

Synthesis of Monofluoromethyl Selenoethers of Aryl and Alkyl from Organoselenocyanate via One-Pot Reaction

The first practical and feasible approach for the monofluoromethylselenolation of aryl and alkyl halides via one-pot multistep synthesis using KSeCN and ICFH2 is described. Good yields and broad functional group compatibility were obtained. The successful preparation of monofluoromethylselenolated drug-like compounds good practicability of this method. This protocol offered a number of new monofluoromethyl selenoethers, which would accelerate the use of such compounds in the areas of life science. (Figure presented.).
