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.

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.

A one-pot, metal-free procedure has been developed to synthesize unsymmetrical organoselenides. In the first step of the reaction, arylation of potassium selenocyanate (KSeCN) with an iodonium reagent proceeds in the absence of a metal catalyst to produce
