摘要:在无水ch3Cn中,一系列9个4-(4-取代-苯甲酰基)-N-甲基吡啶鎓阳离子(取代基:-och3,-Ch3,-H,-Sch3,-Br,-Ctbd1; Ch,-Cho,-No2,和-(+)s(ch3)2)证明了在与其他主流氧化还原催化剂(例如醌和紫精)相同的电势范围内,两种化学可逆的,分离非常好的单电子(1-E)还原反应.哈米特线性自由能图在两个波的e(1/2)值与取代基常数sigma(p)(-)(x)之间产生了极好的相关性.两次1-E还原的反应常数为rho(1)= 2.60和rho(2)= 3.31.较低的rho(1)值与吡啶环的中和相关,而较高的rho(2)值在第二次e还原过程中产生负电荷.结构-功能的相关性指向在两个1-E还原中的纯诱导作用.4-(4-硝基苯甲酰基)-N-甲基吡啶鎓阳离子的情况特别值得注意,因为4-硝基苯甲酰基部分在4-苯甲酰基-N-甲基吡啶鎓体系的第二次还原之前经历了

权利人:UNIV CALIFORNIA; UNIV CALFIORNIA
摘要:The present disclosure relates to the novel multistep procedure for preparation of polymer monoliths for use in solvent exchange, such as methods to exchange and activate fluoride ions on a flow through microfluidic chip for subsequent chemical synthesis. Methods according to the present disclosure include the application of such microfluidic platforms for rapid F18 radiosynthesis on a flow through microfluidic chip with high efficiency, followed by a subsequent nucleophilic fluorination reaction. Various other methods of exchanging and activating fluoride ions on a flow through microfluidic chip are also disclosed. Methods incorporating features of the present invention can be applicable to any flow through microfluidic device in any field, such as radiosyntheses, chemical syntheses, concentration of ions for environmental analyzes and sample preparation such as concentrating minute amounts of analyte to improve the downstream detection.
