to the formation of linear olefins, more preference for elimination toward the less substituted carbon was observed than the selenoxide and sulfoxide eliminations. In the cyclododecyl case only trans-cyclododecene was formed as an olefin componenet in a sharp constrast to the selenoxide elimination that affords a 1:1 mixture of cis and trans isomers. On the contrary, in the n-alkyl and cyclohexyl cases
