Thiocrown etherscontaining thioacetal units are readily prepared by reaction of the cesium salts of long chain dithiols with methylene dibromide. Preparation of the trimethylsilyl derivatives followed by condensation with aldehydes under basic conditions (Peterson reaction) leads to the expected macrocycles with exocyclic double bonds at the thioacetal carbon atom.
