N-(heterocyclicaminocarbonyl)arylsulfonamides, such as N-[(4,6-dimethylpyrimidin-2-yl)aminocarbonyl] benzenesulfonamide, are useful for the regulation of plant growth and as herbicides, particularly for controlling nutsedge.

This letter describes the development of an environmentally benign palladium-catalyzedcross-coupling reaction using heteroaromaticsulfinates as nucleophilic coupling partners in aqueous media. This method accesses aryl-substituted heteroaromatics in very good yields chemoselectively without the need for base, additives or co-catalysts.

Aryl-substituted heteroaromatics were synthesized via desulfinative cross-coupling reactions using aryl triflate and heteroaromatic sulfinate coupling partners. This method uses synthetically versatile aryl triflates to access aryl-substituted heteroaromatics in good yields employing aqueous and alcoholic media without the use of base, additives or co-catalysts.

in simplicity: An efficient and environmentally benign palladium‐catalyzed protocol has been developed using a sulfinate as a nucleophilic coupling partner. The sulfinate position is arylated chemoselectively in very good yields. The bench‐stable, non‐hygroscopic heteroaromaticsulfinate salts rapidly undergo cross‐coupling without the need of a co‐catalyst, base, or additives (see scheme; mw=microwave)
