Dimeric Silver(I) Complexes of Some Isothiazole‐Based Ligands
摘要:
AbstractA series of isothiazole‐based potential ligands bearing substituents with additional donor sites in the 5‐position of the heterocycle was synthesized [3‐Me‐5‐R‐C3HNS; R = CHN(CH2)2py (1), CHNCH2py (2), CH2N(CH2CH2NEt2)2 (4), (CH2)2SMe (5)]. Upon reaction with AgO3SCF3 they formed complexes [(1)AgOSO2CF3]2 (6), [(2)AgOSO2CF3]2 (7), [(4)Ag]2+2(O3SCF−3)2 (8) and [(5)AgOSO2CF3]2 (9), respectively. 6, 8 and 9 were shown by X‐ray structural analyses to consist of dimeric units L2Ag2+2, either discrete (8), coordinated by terminal CF3SO−3 units (6). In 8 and 9 the isothiazole moiety is bonded to the metal center via the ring‐N. The coordination potential of the isothiazole heterocycle is discussed.

Phase transfer catalyzed reductive ring-cleavage acylation of isoxazoles or isothiazoles with acetylcobalt tetracarbonyl gives N-acylated 1-amino-2-alkene-3-ones or thiones. Under the same conditions phthalazine, quinoline and isoquinoline react with acetylcobalt tetracarbonyl to give N-acylated dimers. The reactivity of several other nitrogen-containing heterocycles was also investigated.
