Abstract

key molecule for the synthesis of dibenzotetraselenafulvalene 4. The compound 2a can be obtained in two steps through the reaction of benzyne with dimethyl diselenide, and further condensation with thiophosgene at-8O'C. Non symmetrical structure 2 and the fully sulfurated product 2 are available from the corresponding chalcogenides. These chalcogenides can be obtained by the benzyne way4 (I a, 21 X) or by the tetrafluoroborate ...
