AbstractAn efficient synthesis of alkyl acylcarbamodithioates by reaction of acidchlorides with ammonium thiocyanate in the presence of thiols is described. The unusually large values of 5 J FH = 12–15 Hz, observed for alkyl (2-fluorobenzoyl)carbamodithioates provide information about Ar–C–N–H torsion in these compounds. Graphical Abstract
