A simple and convenient method for the synthesis of 1-dialkylaminocarbothioic acid S-[(2,3-epithio)propyl] ester was developed by the reaction of 1-dialkylaminocarbodithioic acid-sodium salt with 1-chloro-2,3-epoxypropane in water-methanol mixture at room temperature. An intermediate was isolated and characterized, based on which a possible mechanism was proposed.
Synthesis of <i>S</i>-(2-Thioxo-1,3-dithiolan-4-yl)methyl Dialkylcarbamothioate and <i>S</i>-Thiiran-2-ylmethyl Dialkylcarbamothioate via Intermolecular O−S Rearrangement in Water<sup>,</sup>
3-dithiolan-4-yl)methyl dialkylcarbamothioates (3) and S-thiiran-2-ylmethyl dialkylcarbamothioate (5) has been reported by the reaction of 5-(chloromethyl)-1,3-oxathiolane-2-thione (1) with sodium dialkylcarbamodithioate (2) and dialkylamine (4), respectively, through intermolecular O−S rearrangement in water. A plausible mechanism of formation of the title compounds has also been proposed.
