Direct synthesis of sulfinic esters via ultrasound accelerated tandem reaction of thiols and alcohols with N-bromosuccinimide
The direct transformation of various thiols and simple alcohols with N-bromosuccinimide into sulfinic esters has been investigated by using different categories of base/acidic catalysts as well as co-solvents under varied reaction conditions. The reaction was found out to afford the sulfinic esters with high yields in the absence of catalysts, especially within the shorter time under the acceleration of ultrasonic irradiation than under the longer-lasting conventional stirring conditions.

Non-expensive, open-flask and selective catalytic systems for the synthesis of sulfinate esters and thiosulfonates
Two simple and efficient methods for the synthesis of sulfinate esters and thiosulfonates from sodium salts of sulfinic acids are described. Different alcohols were converted into the corresponding sulfinate esters in good yields and purity in an open flask. By the adjustment of the reaction conditions thiosulfonates could also be obtained in a very short reaction time.

SULFINIC ACIDS AND RELATED COMPOUNDS. 15. CONVENIENT METHODS FOR ESTERIFYING SENSITIVE SULFINIC ACID SALTS
In a study of conversions of sensitive sulfinate salts to esters, a trisulfide bissulfinate, 2S (1), was esterified with trialkyloxonium fluorborates.This procedure (Method A) was better for ethylation than use of ROH-HCl/BF3*(C2H5)2O (Metho
