The reaction of tris(t-butylthio)cyclopropenylium perchlorate with phenyl-, o-tolyl-, or 1-naphthylmagnesium bromide in tetrahydrofuran at room temperature gave t-butylthio-substituted allenes and indenes. The reaction with 2,6-xylylmagnesium bromide gave only the corresponding allene derivative.

The reaction between thio-substituted cyclopropenium ions and sulfonium methylides gives unanticipated ketene derivatives. This reaction is supposed to proceed through an intermediate sulfonium salt formed from ylide addition to the cyclopropenyl ring.
