on the activation of C≡O bond by π-back bonding from the transition metal center were developed during the past decades. Herein, a new CO activation method, in which the CO was converted to the active acyl-like metalloradical, [(por)Rh(CO)]• (por = porphyrin), was reported. The reactivity of [(por)Rh(CO)]• and other rhodium porphyrin compounds, such as (por)RhCHO and (por)RhC(O)NH nPr, and corresponding
将一氧化碳 (CO) 转化为石化原料和精细化学品至关重要。在过去的几十年中,开发了许多基于通过过渡金属中心的 π 背键激活 C≡O 键的策略。在此,报道了一种新的 CO 活化方法,其中将 CO 转化为活性酰基类金属基团 [(por)Rh(CO)]• (por = 卟啉)。[(por)Rh(CO)]• 和其他铑卟啉化合物,如 (por)RhCHO 和 (por)RhC(O)NH nPr 的反应性以及相应的机制研究是通过实验和计算进行的,并启发了设计一种具有 100% 原子经济性的新转化系统,可使用卟啉铑 (II) 金属基促进胺羰基化为甲酰胺。遵循这种基于自由基的途径,
