Consecutive Insertion of a Silylene into the P4 Tetrahedron:Facile Access to Strained SiP4 and Si2P4 Cage Compounds

摘要

Organosilicon-phosphorus compounds are versatile building blocks in contemporary organophosphorus chemistry and for the synthesis of metal phosphide semiconducting materi-als or respective molecular clusters.Likewise,cyclic silicon-phosphorus compounds can serve as chelating electron-rich ligands in transition-metal complexes,modeling unusual coordination modes of metal centers in catalysts.
