In my opinion, Cu complexes with unsaturated alcohol to form a complex compound; the nitrogenous compound introduced serves as the complex compound's stabilizing agent and reduces activation energy of reaction; TMPO serves as oxygen carrier and displays it's selective oxidation function. This new method and mechanism also demonstrates significance to other similar organic reactions.3 In the chlorohydrin reaction, NaCIO is replaced by Ca2see Chapter4.4.3.4(2 .A, this method hasn't been reported in previous literature,which exerts more buffer action to the react system, the yield increased from 52% to 88.6%; at the same time it solve the problem of poor stability and low percentage composition of NaCIO.

认为：CuD与烯醇形成络合物：含氮有机物的引入起到稳定络合物，降低活化能的作用：而TMPO则充当携氧子起传递氧的作用，并具有选择氧化功能：这种新的方法和理论对类似的反应(不饱和醇类在络合体系下选择性催化氧化为对应的醛也具有重要的指导作用。3在异戊二烯的氯醇化反应中，用次氯酸钙代替次氯酸钠见第4章4.3.4(2.A，本方法未见文献报道，使反应系统更加温和，收率由52%提高到88.6%：并解决了次氯酸钠稳定性差、有效氯含量低的实际问题，具有重要的实用意义。
