2-Alkenyl-1,3-dithiolan or dithian-2-ylium cations are yielded by hydride abstraction of cyclic ketene dithioacetals with trityl tetrafluoroborate. These cations react with silyl enol ethers or an allylsilane completely regioselectively to give the corresponding functionalized ketene dithioacetals.
