| Application: | Benzenesulfinic acid sodium salt has been used in synthesis of sulfones by reaction of organic halides and sodium benzenesulfinate using higher alcohols or diols as solvents.It was also used in the synthesis of aryl sulfones via copper-catalyzed cross-coupling with boronic acids and vinyl sulfones via reaction with vicinal dibromides. |
| General description: | Benzenesulfinic acid sodium salt when treated with alkynylselenonium salts yields (Z)-β-alkoxyvinylsulfones. It undergoes rhodium-catalyzed desulfinative coupling with aldehydes to yield ketones. |
