摘要：

The reaction of 4-methyl-1,3-dithiane-2-thione with alkyl Grignard reagents or butyllithium (BuLi) at room temperature gave 2-alkyl-4-methyl-1,3-dithianes in good yields. High yields of 2-alkyl-2-butylthio-4-methyl-1,3-dithianes and 2,2-dialkyl-4-methyl-1,3-dithianes were obtained by treatment with BuLi at -78-degrees-C and room temperature followed by alkylation with alkyl halides, respectively.
