preparation of aromatic stannanes from arylhalides (mostly aryl bromides) is presented herein. The reaction proceeds under metal‐ and additive‐free conditions and exhibits a broad substrate scope. The products obtained have been employed in the C‐C bond formation via Stille cross‐coupling reactions. Mechanistic investigation evidenced the key role of both aryl radical and trimethylstannyl radical in

Oxathiino[6,5-b]pyridine 2,2-dioxides are identified as a new class of isoform-selective nanomolar inhibitors of tumor associated human carbonic anhydrases (hCA) IX and XII. At the same time they do not inhibit or poorly inhibit cytosolic isoforms hCA I and II. Oxathiino[6,5-b]pyridine 2,2-dioxides exhibited good antiproliferative properties on tumor cell lines MCF-7 (Human breast adenocarcinoma), A549 (human lung (alveolar) adenocarcinoma) and HeLa (epithelioid cervix carcinoma).
