Neutralization of a Toluene Waste Stream Containing Thionyl Chloride

Neutralization of thionyl chloride in toluene was found to be ineffective with water. A solution is to use an excess of a soluble reagent to consume the thionyl chloride. Butanol was shown to convert thionyl chloride to n-butyl sulfite and hydrogen chloride. An aqueous workup removes any residual hydrogen chloride.

A mild method for conversion of alcohols to dialkyl sulfites by use of Na2SO3/SOCl2

Alcohols are easily converted to their corresponding dialkyl sulfite under mild reaction conditions using Na2SO3/SOCl2 in moderate to good isolated yields.

Solvolysis of N-(Chlorosulfinyl)diarylketimines

N-(Chlorosulfinyl)diarylketimines 1a - c readily react with alcohols, phenols and thiophenol to give good yields of dialkyl sulfites, diaryl sulfites and dithiosulfites, respectively, besides (diarylmethylene)ammonium chlorides 3a - c.The reactions of 1a with water and carboxylic acids have also been studied.

ORGANOSULPHUR COMPOUNDS-LXIX OPTICALLY ACTIVE SULPHINATES: A NEW TYPE OF ENANTIOSELECTIVE ASYMMETRIC SYNTHESIS AND KINETIC RESOLUTION

Optically active sulphinates with the sulphur atom as a sole centre of chirality are prepared by two methods.The first involves the reaction of symmetrical sulphites with tert-butylmagnesium chloride in the presence of optically active aminoalcohols.This new asymmetric, enantioselective synthesis affords t-butylsulphinates with 40-70percent enantiomeric excess values.The second approach is based on a new type of kinetic resolution taking place when racemic sulphinates are reacted with tert-butylmagnesium chloride complexed by optically active alkaloid bases.Both the recovered sulphinates and sulphoxides formed in this reaction show moderate optical purities.
