A method for preparing 1,4-(Z,Z)-disubstituted-1,4-disulfurated-1,3-butadienes is disclosed. The butadienes can be further elaborated to provide 3,6-unsymmetrically-substituted-1,2-dithiins. Also disclosed are butadienes prepared by the method of the invention. These butadienes are useful as intermediates in the synthesis of antibiotic 1,2-dithiins.
