PYROTHIOCARBONATES V. SYNTHESIS AND SOME REACTIONS OF S-TRIMETHYLSILYL O-ALKYLDITHIOCARBONATES

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.

Investigations on the Behaviour of Potassium n-Butyl Xanthate and Benzamidothiosemicarbazide at D.M.E.

Potassium n-butyl xanthate (PNBX) and benzamidothiosemicarbazide (BTSC) were studied at d.m.e.The polarographic studies carried out on the behaviour of PNBX and BTSC consist of the effect of concentration, pH, supporting electrolytes and mercury column heights.These waves were found to be diffusion controlled.In case of PNBX, E1/2 (-0.22 volts) remained constant with the increase in pH, while in case of BTSC E1/2 increased continuously with the increase in pH.Besides the studies on reversibility of the process, logarithmic analysis of the wave yielded straight lines with mean slope ratio of 0.033 volts (PNBX) and 0.032 volts (BTSC), showing reversible and two electron transfer process.The pK value (8.0) of BTSC has been evaluated from pH vs -E1/2 plot.The mechanism of the dimerisation of these compounds has been proposed.
