An in situ-generated bissilylated sulfonium ion is the actual catalyst in highlyregio- and diastereoselectiveaddition reactions of thiosilanes across the C−C multiple bonds of alkynes and allenes, respectively (see scheme). These thiosilylation reactions enable the direct installation of two orthogonal linchpins for further chemoselective functional-group manipulation.
