Abstract A series of new of photochromic 1,3-diazabicyclo[3.1.0]hex-3-ene derivatives based on the skeleton of five-membered pyrazole moiety have been synthesized and characterized by spectral techniques, as well as their photochromic properties were examined under UV light irradiation in various solutions. All these newly synthesized compounds showed good photochromic properties in the both solution

AbstractA series of 1-(pyrimidin-2-yl)hydrazine-1-carbonitriles was synthesized by base-catalyzed condensation of 3,4-diamino-1,2,4-triazole hydrobromide with several 1,3-dinucleophilic compounds. These final products were formed by ring opening of the 1,2,4-triazolium ring via intermediate 3-amino[1,2,4]triazolo[1,5-a]pyrimidinium bromides. Graphical Abstract
摘要通过3,4-二氨基-1,2,4-三唑氢溴酸盐与几种1,3-二亲核化合物的碱催化缩合反应,合成了一系列1-(嘧啶-2-基)肼-1-腈。这些最终产物是通过中间体3-氨基[1,2,4]三唑并[1,5- a ]嘧啶溴化物开环1,2,4-三唑鎓环而形成的。 图形概要
