Abstract

The planar, non-twisted distannene Sn(TIPS) (, TIPS = SiPr) reacts with CS to form a tetrathiaethylene derivative via the dimerization of two S-heterocyclic carbenes (SHCs). These intermediary-formed SHCs can be transferred to palladium as ligands or captured with B(CF) (BCF) and, furthermore, facilitate a new pathway for formation of the stannaethene SHC═Sn(TIPS) by the reaction of with (PPh)Pd-CS. In addition to the characterization of the new complexes, theoretical calculations of the frontier orbitals were performed, which indicate a high π-acceptor character of the SHC.

摘要

平面、非扭曲的二锡烯Sn(TIPS)（TIPS = SiPr）与CS反应，通过两个S-杂环卡宾（SHC）的二聚作用形成一种四硫代乙烯衍生物。这些中间形成的SHC可以作为配体转移到钯上，或被B(CF)（BCF）捕获，此外，还通过与(PPh)Pd-CS反应促进了形成锡烯SHC═Sn(TIPS)的新途径。除了对新配合物进行表征外，还进行了前沿轨道的理论计算，结果表明SHC具有高π受体特性。
