Palladium-catalyzed one-step synthesis of symmetrical diaryl sulfones from aryl halides and a sulfur dioxide surrogate

A convenient method for the one-step synthesis of symmetrical diaryl sulfones from aryl halides has been developed. A keystone of the method is the use of K2S2O5, which can be easily and safely handled, as a sulfur dioxide surrogate. The palladium catalyst bearing P(t-Bu)3 as a ligand enables formation of the desired sulfones without significant formation of byproducts.

Identification and quantitation of dinaphthylsulfones in particulate matter of the Elbe river, Germany: Part VI of organic compounds as contaminants of the Elbe river and its tributaries

Gas chromatographic-mass spectrometric (GC/MS) analysis of particulate matter of the Elbe river and its tributaries Havel, Spree and Mulde revealed a group of three dinaphthylsulfone isomers as sedimentary and suspended particulate matter (SPM) contaminants. The mass spectra of dinaphthylsulfones are characterized by the molecular ion (m/z 318), and the naphthyl fragment ion m/z 127. Losses of HSO2 and C10H7O from the molecular ion lead to different mass spectra for each isomer. The gas phase infrared spectra exhibit isomer specific bands in the spectral region between 900 and 700 wave numbers. A synthetic mixture of dinaphthylsulfones was used for isomer identification and the assignment of the gas chromatographic retention behaviour of the dinaphthylsulfone isomers. Quantitative GC/MS analysis of dinaphthylsulfones in 44 sediment and SPM samples provided comprehensive information on the overall distribution and distinct sources of dinaphthylsulfones in the Elbe river drainage system. The results indicate emissions of these compounds over prolonged times and their environmental stability in anaerobic sediments.
