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.

The invention relates to medicine, in the field of organic chemical and fine chemical industry, and in particular relates to a simple, highly efficient method for preparing aryl sulfonic acid ester compound. The method is to four fluoro boric acid aryl diazonium salt, double-(sulfur dioxide) - 1, 4 - diazabicyclo [2.2.2] octane adduct (DABSO) and alcohol as the raw material, the copper salt catalyst, under the presence of an oxidant, nitrogen protection, 50 - 100 °C heating under the reaction conditions, it took 10 - 15 hours synthetic aryl sulfonate. The reaction through simple after treatment can be a high yield a series of aryl sulfonic acid ester compound. On the benzene ring with various substituted aryl four fluoroborates, ordinary primary alcohol, secondary alcohol can be utilized as a reaction substrate, to obtain the corresponding asia sulfonic acid ester.

A mild and efficient one-pot visible light-induced method has been developed for the synthesis of sulfinic esters. Sulfinic esters are important structural elements that are frequently found in pharmaceutical agents and biologically active natural products. The routine procedure in the drug discovery and development process to prepare and fully characterize sulfinic esters make them a drug candidate for biological evaluation.
