Dichlorodimethylsilane → Chloro-dimethyl-(2-phenylethynyl)silane

Participants

Reaction Steps

A suspension of phenylethynyllithium was prepared by the dropwise addition over 1 hour of 16 parts of a 1.0 mol/L solution of n-butyllithium in hexane to 23 parts of phenylacetylene dissolved in 100 parts of ethyl ether. This suspension was gradually added dropwise over a period of 1 hour to a mixture of 60 parts dimethyldichlorosilane and 100 parts ether. After removal of the lithium chloride by filtration, distillation of the filtrate yielded 30 parts phenylethynyldimethylchlorosilane.
