photoinduced oxidation reaction of 11a,b+·BF4- and 12a,b+·BF4- toward some amines under aerobic conditions was carried out to give the corresponding imines (isolated by converting to the corresponding 2,4-dinitrophenylhydrazones) with the recycling numbers of 0.6−30.3. Furthermore, as an example of the NAD+-NADH models, the reduction of a pyruvate analogue and some carbonyl compounds with the hydride-adduct
一种方便的新型阳离子11a,b +的制备· BF 4 -和12a,b +· BF 4 -,其衍生自1,3-二甲基环庚[4,5]吡咯并[2,3- d ]嘧啶-2,4(1,3 H)-二重氮离子与其他吡咯并[2,3- d ]的环化嘧啶-1,3(2,4 H)-二酮和呋喃类似物是通过1,7-二氢-7- [1',3'-二甲基-2',4'(1 ”,3' ħ) -二氧代-6' - (苯基氨基) -嘧啶-5'-基] -1,3-二甲基-10- phenylcyclohepta [4,5]吡咯并[2,3- d ]嘧啶-2, 4(1,3 H)-dione 9及其呋喃类似物通过在有氧条件下使用DDQ或光辐照。11a,b +的结构特征和12a,b +在检查UV-vis和NMR光谱数据以及X射线晶体分析时得到澄清。阳离子11a,b +的稳定性和12a,b +用分光光度法测定的p K R +值表示为10.7-12.6。电化学还原11a,b
