Abstract
The preparation of methyl dithioacetate via methylmagnesium bromide is well known,'and its use for the preparation of 1, 2-dithiole-3-thione 1 according to Scheme I was reported recentlya2 We, independently, studied this sequence of reactions but with a different base and slightly different conditions. In Scheme I, B: is either sodium methyl dithioacetate or an excess of sodium hydride. If the chemical transformations depicted in Scheme I for methyl ...
