BENZENESULFINIC ACID SODIUM SALT Usage And Synthesis
Chemical Propertieswhite crystalline powder or crystals
UsesBenzenesulfinic 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.
UsesIt is used as a polymer adhesive enhancers, plasticizers for plasticized and modified of polyamide, epoxy resin, phenolic resin. It is designed for manufacturing of photography, pharmaceutical, electroplating industry, can be used as photo-reducing agent.
UsesBenzenesulfinic Acid Sodium Salt is used reduce the adverse chemical interaction involved in the coupling of self/dual-cured composites to hydrated dentin.
General DescriptionBenzenesulfinic acid sodium salt when treated with alkynylselenonium salts yields (Z)-β-alkoxyvinylsulfones. It undergoes rhodium-catalyzed desulfinative coupling with aldehydes to yield ketones.
Purification MethodsDissolve 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.
