Some novel sulfur bridged 13- to 30-membered cyclic di- and tetraalkynes derived from 1,2-, 1,3- and 1,4-dihydroxybenzene and 1,2-bis(bromomethyl)benzene were synthesized and their structures confirmed by X-ray analysis. The unexpected formation of 2,6-divinyl-1,4-dithiin during Na2S/alumina induced cyclization was also observed and the reaction mechanism is discussed.
