In the present study, we report the photochemical transformation of pyrazolo[1,2-a]pyrazolone substrates that reach an excited state upon irradiation with visible light to initiate the homolytic C–N bond cleavage process that yields the corresponding N1-substituted pyrazoles. Moreover, chemoselective heterolytic C–N bond cleavage is possible in the pyrazolo[1,2-a]pyrazole core in the presence of bromomalonate
在本研究中,我们报道了吡唑并[1,2- a ]吡唑啉酮底物的光化学转化,该底物在可见光照射下达到激发态,引发均裂 C-N 键裂解过程,产生相应的 N1 取代吡唑。此外,在溴丙二酸存在下,吡唑并[1,2- a ]吡唑核心可能发生化学选择性异裂C-N键断裂。
