What is BENZENESULFINIC ACID SODIUM SALT?

Chemical properties

white crystalline powder or crystals

The Uses of BENZENESULFINIC ACID SODIUM SALT

Benzenesulfinic Acid Sodium Salt is used reduce the adverse chemical interaction involved in the coupling of self/dual-cured composites to hydrated dentin.

The Uses of BENZENESULFINIC ACID SODIUM SALT

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.

Purification Methods

Dissolve it in the minimum volume of O2 free H2O (prepared by bubbling N2 through for 2 hours) and adding O2 free EtOH (prepared as for H2O), set aside at 4o overnight under N2, filter, wash with EtOH, then Et2O and dry in vacuo. The Na salt is relatively stable to air oxidation, but is best kept under N2 in the dark. Also recrystallise it from EtOH and dry it at 120o for 4hours in a vacuum.
