Sulfuryl chloride → 2-(4-Methylphenyl)-1,3-dithiolanium chloride

Participants

Reaction Conditions

Reaction Steps

A solution of 1.96 g (0.01 mole) of 2-(4-methylphenyl)-1,3-dithiolane in 20 ml of methylene chloride is cooled to 0° C. and 0.76 ml (0.0094 mole) of sulfuryl chloride is added in one portion. The mixture is stirred 1 hr at 5° C. It is diluted with methylene chloride and the ultraviolet spectrum measured: U.V. max 230,255,375 nm, the latter indicating the presence of 2-(4-methylphenyl)-1,3-dithiolanium cation.
