文摘

The archetypal 3,1,2,4-benzothiaselenadiazine, its 5- and 8-Me3Si derivatives and related dithiadiazine and trithiadiazepine were synthesized from 2-Me3SiC6H4N=S=NSiMe3 by the action of SeCl2, SeCl4, SCl2, and S2Cl2 and converted into persistent 2,1,3-benzothiaselenazolyl and 1,2,3-benzodithiazolyl radicals characterized by EPR spectroscopy and DFT calculations.
