研究了二硫烯配体 qpdt(2-)（生物钼蝶呤辅助因子的模拟物）和相应的 (eta(5-)环戊二烯基)钴 (III) 络合物 [(qpdt) (CoCp)-Cp-III] 的还原。结果发现，在这两种情况下，在酸性介质中都发生了前所未有的断环反应。所有新反应产物均已进行光谱和结构表征。还提出了这些产物形成的合理机制。
The reduction of the dithiolene ligand, qpdt(2-),a mimic of the biological molybdopterin cofactor, and the corresponding (eta(5-)cyclopentadienyl) cobalt( III) complex [(qpdt) (CoCp)-Cp-III] was studied. It was found that in both cases an unprecedented ring scission reaction took place in acidic medium. All new reaction products have been spectroscopically and structurally characterized. Plausible mechanisms for the formation of these products were also proposed.
