We have developed a protocol for the NaHSO3-promoted esterification of sulfonyl hydrazides with alcohols for the synthesis of sulfinic esters. Various sulfonyl hydrazides could be converted to the corresponding sulfinic esters in good to high yields. The merits of this protocol include mild transition-metal-free reaction conditions, an inexpensive and available reagent, and operational simplicity. Controlled experiments reveal that this transformation probably undergoes via a radical pathway. (Figure presented.).

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.
