and regioselectivity. The reaction was studied for a series of substrates and the absolute regioselectivity of a representative triazole product has also been confirmed by X-ray crystallography. The proficiency and chemical orthogonality of the Ni-TLOP are remarkable and it shows enhanced efficiency and regioselectivity. The use of a recyclable photocatalyst and non-hazardous reagents makes the catalytic
在寻找独特而有效的催化剂以使该过程高效,绿色和可持续的过程中,对药用活性1,2,3-三唑的合成一直进行了严格的审查。在这里,我们提出了一种新的可见光活性镍(II)Cyclam集成的三唑连接的有机聚合物(Ni-TLOP)光催化剂,具有出色的效率和区域选择性,可合成1,2,3-三唑化合物。研究了一系列底物的反应,并且还通过X射线晶体学证实了代表性三唑产物的绝对区域选择性。Ni-TLOP的熟练度和化学正交性非常出色,并且显示出更高的效率和区域选择性。可循环使用的光催化剂和非危险试剂的使用使催化系统具有可持续性和环境友好性。这种光催化的点击反应技术已成功应用于最畅销的抗癫痫药rufinamide的合成。
