with carbondisulfide in the presence of bases. These compounds were tested for the inhibition of four human (h) isoforms of the zinc enzyme carbonic anhydrase, CA (EC 4.2.1.1), hCA I, II, IX, and XII, involved in pathologies such as glaucoma (CA II and XII) or cancer (CA IX). Several low nanomolar inhibitors targeting these CAs were detected. The X-ray crystalstructure of the hCA II adduct with morpholine

converts it to SnCl2I. The iodide counter-anion in II may be replaced by others to give [BPh4]−, [Co(CO)4]− or [NO3]− salts. However [CN]− acts differently and displaces (PhO)3P from [Co(η-C5H5)P(OPh)3}(S2CNMe)]I to give [Co(η-C5H5)(CN)(S2CNMe2)] which may be alkylated reversibly by MeI and irreversibly by MeSO3F to [Co(η-C5H5)(CNMe)(S2CNMe2)]+ salts.
