The conversion of tetrazolo[1,5-a]quinoxalines to 1,2,3-triazoloquinoxalines and triazoloimidazoquinoxalines under typical conditions of a CuAAC reaction has been investigated. Derivatives of the novel compound class of triazoloimidazoquinoxalines (TIQ) and rhenium(I) triazoloquinoxaline complexes as well as a new TIQ rhenium complex were synthesized. As a result, a small 1,2,3-triazoloquinoxaline
已经研究了在典型的 CuAAC 反应条件下四唑并[1,5 - a ]喹喔啉向 1,2,3-三唑并喹喔啉和三唑并咪唑并喹喔啉的转化。合成了新型三唑并咪唑喹喔啉 (TIQ) 和铼 (I) 三唑并喹喔啉配合物的衍生物以及新的 TIQ 铼配合物。结果,获得了一个小的 1,2,3-三唑并喹喔啉库,该方法可以扩展到 4-取代的四唑并喹喔啉。研究了各种脂肪族和芳香族炔烃对该反应的相容性,并且可以观察到对咪唑并喹喔啉的脱氮环化反应作为竞争反应,这取决于炔烃浓度和喹喔啉的取代。
