On December 3, 2021, Jo, Hwi Yul; Lee, Jeong Min; Pietrasiak, Ewa; Lee, Eunsung; Rhee, Young Ho; Park, Jaiwook published an article.Safety of H-Phg(4-OH)-OH The title of the article was Generation of N-H imines from α-Azidocarboxylic Acids through Ru-catalyzed Decarboxylation. And the article contained the following:
A new method for the synthesis of N-H imines from α-azidocarboxylic acids was developed, which proceeded through decarboxylative C-C bond cleavage catalyzed by a com. diruthenium complex ([CpRu(CO)2]2) under visible light irradiation at room temperature within several minutes. The reactive products undergo condensation forming cyclic trimers (2,4,6-trialkylhexahydro-1,3,5-triazines) or linear N,N’-bis(arylmethylidene)arylmethanediamines in quant. yields. Alternatively, the N-H imines was trapped with benzylamine and 2-(aminomethyl)aniline providing stable N-benzylimines and tetrahydroquinazolines, resp. Subsequent oxidation of tetrahydroquinazolines produced quinazolines. The experimental process involved the reaction of H-Phg(4-OH)-OH(cas: 32462-30-9).Safety of H-Phg(4-OH)-OH
The Article related to azidoethanoic acid ruthenium catalyzed decarboxylation condensation, hexahydrotriazine bismethylidenemethanediamine preparation, benzylmethylidene amine preparation, quinazoline preparation and other aspects.Safety of H-Phg(4-OH)-OH
