Abstract

A new heterocyclic four-membered CPSeSi cation was synthesized in its racemic form by B(C6F5)3-mediated ring-closing reaction starting from the hydrosilane precursor. The cation has an asymmetrically substituted silicon center, which is stabilized by a selenium–silicon bond. The phosphonium hydroborate and its precursor were characterized by single-crystal X-ray diffraction analysis and NMR ...
