Using fluoroform for constructing aromatic and heterocyclic trifluoromethylselenyl compounds

Fluoroform is used to prepare CuCF3 according to literature procedures. This nucleophilic trifluoromethyl moiety was reacted with aromatic and heterocyclic selenium cyanide derivatives to form the corresponding trifluoromethylselenium compounds. Selenium cyanides were made with 1,3-dicyanotriselenide prepared in situ from malononitrile and selenium dioxide. The electrophilicity of the reagent (δ+SeCN) was enough to attack aniline derivatives at the para position, but with other aromatics it was advantageous to use the corresponding boronic acid as the moiety was easily displaced by the selenium cyanate moiety.

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.

Metal-Free ipso -Selenocyanation of Arylboronic Acids Using Malononitrile and Selenium Dioxide

The first ipso -selenocyanation of arylboronic acids is achieved using selenium dioxide and malononitrile under mild conditions. The reaction is successful even without metal or base in DMSO. The major advantages of this new method are an easy set-up, excellent yields, and the use of odorless and inexpensive selenium reagents. Basic conditions subsequently afford new access to diaryldiselenides in good yields without isolating the organoselenocyanate intermediates.
