Article abstract of DOI:10.1039/c39910000369

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 , from which several members of a new family of S2N2C-CN2S2ⁿ⁺ (n=0,1,2) bicyclics have been prepared.
