Substrate- and temperature-controlled divergence in reactions of alcohols with TosMIC catalyzed by BF3 · Et2O: Facile access to sulfinates and sulfones

An efficient BF3 · Et2O-catalyzed divergent synthesis of sulfinate esters and sulfones through C–O and C–S bond formation has been achieved from alcohols and p-toluenesulfonylmethyl isocyanide (TosMIC). Various alcohols reacted smoothly with TosMIC under the present conditions at room temperature providing sulfinate esters exclusively. By tuning the reaction temperature, the alcohols that provide highly stabilized carbocation in the reaction medium afforded sulfones as sole products. This study was aimed at understanding the regioselectivity of ambidentate sulfinate ion and to elucidate the interpretation of sulfinate/sulfone scaffolds.

OXIDATION OF N-ALKYL-N'-TOSYLHYDRAZINES WITH BROMINE

Oxidation of N-alkyl-N'-tosylhydrazines with bromine yield alkyl bromides, vicinal alkyl dibromides and traces of alcohols.The main products of primary hydrazines are monobromides whereas secondary hydrazines preferably produce dibromides.The reaction proceeds with evolution of nitrogen and hydrobromic acid and by the formation of intermediate sulfinic ester wich may be isolated.Various substrates were examined under different conditions to confirm the validity of the reaction mechanism hypothesized.
