Abstract: Aryl sulfinates are precursors to a diverse number of sulfonyl-derived arenes, which are common motifs in pharmaceuticals and agrochemicals. Here, we report a site-selective two-step C–H sulfination sequence via aryl sulfonium salts to access aryl… read more here.

Abstract: A photocatalytic sulfamoylation/5-endo-trig cyclization of (E)-N'-arylidene-N-phenylmethacrylohydrazides with sulfamoyl chlorides was developed. The chemoselective intramolecular addition of the carbon-centered radical intermediate to the CN bond in the hydrazone motif gave the sulfamoylated pyrazolin-5-one. Besides, sulfonyl chlorides… read more here.
