Insertion of LiPEt2 into poly(dimethylsiloxane) to give [LiOSiMe2PEt2]6
Abstract
The hexameric structure of the product of the reaction of lithium diethylphosphide 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.
