  Photochemistry of Nitrosyl Metalloporphyrins:  Mechanisms of the Photoinduced Release and Recombination of NO

  摘要：

  A series of substituted nitrosylmetalloporphyrins of the type M(NO)(meso-tetra(p-X)phenylporphyrin) (M Co, Mn; X = H, NO2, OMe) were prepared and studied by laser flash photolysis. The kinetics of the recombination reactions between the metalloporphyrins and NO in THF were examined. The recombination mechanism appears to be more complicated than the simple second-order process previously reported. Out-of-plane puckering of the porphyrin ring immediately after denitrosylation is one possible explanation. Kinetic experiments and NO transfer studies between manganese and cobalt porphyrins suggest that these compounds exist in equilibrium with NO in solution. Varying the substituents in the phenyl ring of the tetraphenylporphyrin ligand has little effect on rates of recombination with NO.

  A Green Process for Oxidation of p-Nitrotoluene Catalyzed by Metalloporphyrins under Mild Conditions

  摘要：

  A novel synthetic technology of p-nitrobenzoic acid has been investigated with dioxygen by using metalloporphyrins RTPP-(MCl)-Cl-III (M = Fe, Co, Mn) as biomimetic catalysts. Oxidation of p-nitrotoluene to p-nitrobenzoic acid under 2.0 MPa of O-2 in the presence of a microamount of metalloporphyrins (RTPP-(MCl)-Cl-III) at 55 degrees C was achieved with the highest ( up to 90.4%) yield. Further research results show that the catalytic activities were relative to the nature of the substituted groups and the central metal ions of metalloporphyrins. For the metalloporphyrins with the same center metal ions, the greater the electron-withdrawing degree of groups in the porphyrin ring, the higher the catalytic activities of the metalloporphyrins. The catalytic activities for metalloporphyrins with different center metal ions followed the order RTPPMn Cl-III > RTPP (FeCl)-Cl-III > RTPP (CoCl)-Cl-III.

  本发明公开了一种醛和吡咯缩合及二价锰盐氧化插入反应同步合成四芳基锰卟啉的方法，该方法由芳香醛、吡咯和二氯化锰在无水三氯化铝催化下，在DMF溶剂中回流一步合成四芳基锰卟啉。反应过程为：搅拌下依次加入无水三氯化铝、芳基醛、吡咯和二氯化锰到DMF中，加热回流反应一定时间后停止反应，降温，在273K附近放置过夜，抽滤得到卟啉锰紫黑色晶体。该方法直接使用芳香醛、吡咯和二氯化锰为原料，不需要使用卟吩，不使用强腐蚀性有机酸作溶剂，在无需采用复杂分离手段的条件下，高产率获得高纯度四芳基锰卟啉，易于实现工业化生产。
