.beta.-(N,N-Dialkylamino)ethyl arylthiosulfonates: new simulants for O-ethyl S-[2-(diisopropylamino)ethyl] methylphosphonothioate
摘要:
Beta-(N,N-Dialkylamino)ethyl arylthiosulfonates 2, new simulants for the hydrolysis and oxidation chemistry of VX (1), are prepared in good yield by reaction of a potassium arylthiosulfonate with a 2-chloroethylamine. Alkaline hydrolysis of 2 results in cleavage of the S-S bond to give sulfinic acids and disulfides. Like VX, oxidation of 2 by N-sulfonyloxaziridine 12 occurs exclusively on nitrogen to give the corresponding amine oxide which subsequently undergoes a Cope elimination reaction affording the vinyl sulfide 14.

intermolecular difunctionalization strategy of styrenes with methyl thiosulfonates and arylboronic acids has been developed. This method provides an efficient and straightforward avenue to a broad range of 2,2-diarylethyl sulfone derivatives from readily available methyl thiosulfonates and commercially available styrene and arylboronic acid derivatives. The diverse substrate scope attests to the high

Rhodium(II)/phosphine-cocatalyzed bis-sulfuration of α-diazocarbonyl compounds using thiosulfonates as the sulfenylating agent, which provided two sulfur-containing moieties, was developed via simultaneous inter- and intra-molecular C–S bond formation. This novel protocol provides a rapid syntheticroute to dithioketal derivatives in moderate to good yields in an atom-economic process. The transformation
