摘要
The rates of cycloaddition reactions of SNSAsF6 with alkynes and nitriles increase as the ionization potential (E(i)) of the triple bond decreases, and accordingly reaction with HCCCN occurs preferentially at the CC bond; however, it reacts with NCCN quantitatively to give the dication (CactivativeNSNS)2(2+), from which several members of a new family be S2N2C-CN2S2n+ (n = 0,1,2) bicyclics have been prepared.
