only 5 and 15 min in ethanol. Molecular oxygen insertion in 5 and 10 is monitored and forms mixture of products within 5 min. The crystal structure of 1, 4, 5, 6, 8 and 10 is reported. Benzyl ring is oriented over dmgH wing in both 5 and 10 and has a weak C–H…π interaction (3.33 Å and 3.22 Å) and this causes high upfield shift of the dmgH protons. Electrochemical study on 1, 4, 5, 6, 8 and 10 is also
已经合成了十种混合的二肟配合物RCo(L)(dmgH)Py [R = Cl,Me,Et,Bu,苄基] [L = dSPhgH(1-5)和dSEtgH(6-10)],并通过NMR进行了表征。1和6的形成非常快,在乙醇中仅需5和15分钟。监测5和10中的分子氧插入情况,并在5分钟内形成产物混合物。的晶体结构1,4,5,6,8和10进行报告。苄基环在5和10中都位于dmgH机翼上方并具有弱的C–H…π相互作用(3.33Å和3.22Å),这会导致dmgH质子的高场偏移。电化学研究1,4,5,6,8和10还报道。由于SEt基团增加了电子给体,因此6比1更难还原。
