  General Synthesis of Trifluoromethyl Selenides Utilizing Selenocyanates and Fluoroform

  摘要：

  Trifluoromethylated selenoethers are quite rare despite their potential and the interest that they generate. A series of trifluoromethylseleno derivatives, either primary and secondary aliphatic or aromatic and heterocyclic, is described herein by the reaction of easily prepared organic selenocyanates and CuCF3. Another beneficial feature of this reaction is the use of fluoroform as a source for the CF3 group, a compound whose chemistry is currently being intensively researched because it is a potent greenhouse gas that should not be released into the atmosphere.

  Available online-1-n-butyl-3-methylimidazolium selenocyanate ([bmim][SeCN]) proved to be a very efficient reagent for selenocyanation of alkyl halides. As part of an eco-friendly process, no organic solvents were used during the transformation and reaction times are reduced by using microwave as a heating source. The ionic liquid was carefully recycled in two different ways. Selenocyanate compounds

  A direct trifluoromethylselenolation of alcohols with the readily accessible [Me4N][SeCF3] salt has been reported. The reaction is significantly promoted by CaCl2 and proceeds smoothly through unprecedented carbonoselenoate intermediates to form the corresponding alkyl trifluoromethyl selenoethers in good yields. This protocol is also applicable to the late-stage dehydroxytrifluoromethylselenolation of complex alcohols owing to its mildness, good compatibility, high efficiency, and broad functional group tolerance.
