Formation, characterization and reactivity of a selenaza dication [R2Se+–N+R3] from N-methyl-5H,7H-dibenzo[b,g][1,5]selenazocine
Abstract
A new heterocycle containing selenium and nitrogen atoms, N-methyl-5H,7H-dibenzo[b,g][1,5]selenazocine 1, has been synthesized; the reaction of the selenoxide of 1 with (CF3SO2)2O gave a novel selenaza dication salt which was characterized by 77Se NMR spectroscopy, and the dication acts as an oxidizing agent.
