Insertion of LiPEt2 into Poly(dimethylsiloxane) to Give (LiOSiMe2PEt2)6

摘要

The hexameric structure of the product of the reaction of lithiumdiethylphosphide with poly(dimethylsiloxane) (silicone stopcock grease) has been determined by X-ray crystallography; it forms a distorted hexagonal prism with the vertices occupied alternately by lithium and oxygen atoms. lithium diethylphosphide, poly(dimethylsiloxane), insertion.
