Highly Unsaturated Macrocyclic Silahydrocarbons Contining Exocyclic Phenyl Groups

摘要

A series of 12- and 18-membered macrocycloethynes and macrocyclosilethenesilethynes,containing peripheral methyl and phenyl groups was prepared by organomagnesium synthesis under conditions of high dilution.One of these compounds contains an endocyclic 1,4-phenylene bridge.
