Reaction Conditions:

with hydrazine hydrate;sodium carbonate in water at 30; for 2 h;

Steps:

6
General procedure: A preparation method of substituted sulfinate, taking benzenesulfonyl chloride hydrolysis and reduction to obtain sodium benzenesulfinate as an example:Add 20.1g (0.402mol) of hydrazine hydrate to 300g of water, add 40.8g (0.385mol) of sodium carbonate and dissolve at a temperature of 60.After 111 g (0.629 mol) of benzenesulfonyl chloride was added dropwise, the reaction was incubated for 2 hours, and the synthetic solution was cooled and filtered to obtain the sodium salt of benzenesulfinic acid. The purity was analyzed by HPLC. The results are summarized in Table 1.
