1. Denitrative Sulfonylation of Nitroarenes with Sodium Sulfinates.

Author

Da Luz, Jonathan, Čierna, Michaela, Cooper, Bradley D., Harris, Thomas D., Lim, Ethan R. X., Carney, Jonathan R., and James, Michael J.

Subjects
*NITROAROMATIC compounds, *SULFINATES, *SULFONES, *SODIUM, *CARBONATES
Abstract

A one-step method to convert nitroarenes into aryl sulfones under operationally simple, transition-metal-free conditions is described. A range of nitroarenes were reacted with sodium sulfinates and caesium carbonate in N , N ′-dimethylpropyleneurea to afford aryl sulfones in up to 83% yield. [ABSTRACT FROM AUTHOR]

Abstract

A one-step method for the conversion of nitroarenes into phenols under operationally simple, transition-metal-free conditions is described. This denitrative functionalization protocol provides a concise and economical alternative to conventional three-step synthetic sequences. Experimental and computational studies suggest that nitroarenes may be substituted by an electron-catalysed radical-nucleophilic substitution (SRN1) chain mechanism. [ABSTRACT FROM AUTHOR]
