The desulfitative synthesis of aryl ketones from nitriles was also compared to the corresponding transformation starting from benzoic acids. Comparison of the energy profiles indicates that the free energy requirement for decarboxylation of 2,6-dimethoxybenzoic acid and especially benzoic acid is higher than the corresponding desulfitative process for generating the key aryl palladium intermediate.

sulfonylation of thiols was performed by using sodium sulfinates under an oxygen atmosphere. The procedure afforded thiosulfonates in good yields by using a CuI–Phen·H2O (Phen = 1,10-phenanthroline) catalyst and tolerated numerous combinations of arene- and alkanethiols with sodium sulfinates. Furthermore, it was found that the coupling of diaryl disulfides with sodium arylsulfinates proceeded in air and both

Provided herein are small molecule activators of Nicotinamide Phosphoribosyltransferase (NAMPT), compositions comprising the compounds, and methods of using the compounds and compositions.
Preparation of arylthiocyanates by simply mixing aromatic sulfinates with cyanotrimethylsilane (TMSCN) was achieved in good to moderate yields. The thiocyanates were also obtained directly from sulfonyl chloride using TMSCN, sodium sulfite, and potassium carbonate.

A novel and convenient palladium‐catalyzed cross‐coupling reaction of H‐phosphonate diesters with sodiumarylsulfinates was developed via desulfitation in the presence of silver carbonate and tetra‐butylammonium chloride. This method is highly efficient and provides a rapid access to a broad spectrum of arylphosphonate diesters in good to excellent yields.
