report a cascaded oxidative sulfonylation of N-propargylamine
via a three-component coupling reaction using DABCO·(SO2)2 (DABSO). 3-Arylsulfonylquinolines were obtained
by mixing diazonium tetrafluoroborate, N-propargylamine,
and DABSO under argon atmosphere in dichloroethane (DCE) for 1 h.
In a radical pathway, DABSO was utilized as the sulfone source and
an oxidant in this radical-mediated cascaded reaction.
