Sumario:[Image: see text] Inspired by the proposed inner-sphere mechanism of the tungstoenzyme acetylene hydratase, we have designed tungsten acetylene complexes and investigated their reactivity. Here, we report the first intermolecular nucleophilic attack on a tungsten-bound acetylene (C(2)H(2)) in bioinspired complexes employing 6-methylpyridine-2-thiolate ligands. By using PMe(3) as a nucleophile, we isolated cationic carbyne and alkenyl complexes.
