Non-reported S-trimethylsilyl-O-alkyldithiocarbonates (2) are prepared by reaction of O,O-dialkyltrithiodicarbonates with N-methyl-N-trimethylsilylaniline in 87-96percent yield.These air-sensitive liquids which are separated from accompanying phenyl methyl alkylcarbamothioates by fractional distillation.The reaction of 2 with acetyl chloride gives the unsymmetrical dithioanhydrides S-acetyl O-alkyldithiocarbonates in 93-97percent yield.With the less powerfull electrophilic reagent, iodomethane, S-trimethylsilyl O-ethyldithiocarbonate (2a) forms S-methyl O-ethyldithiocarbonate in 30percent yield.When a chloroform solution of 2a is stirred with water the unstable compound O-ethyldithiocarbonic acid is obtained. Key words: Masked O-alkyldithiocarbonic acids; O,O-dialkyltrithiodicarbonates; S-acetyl O-alkyl-dithiocarbonates.
