Protonation direction of 3-allylthio[1,2,4]triazino[5,6-b]indole and 3-methyl[1,3]thiazolo[3′,2′:2,3][1,2,4]triazino[5,6-b]indole
摘要:
X-ray diffraction studies have demonstrated that the protonation of 3-allylthio-5H-[1,2,4]triazino-[5,6-b]indole with hydrogen halides occurs at N-2 and that of 3-methyl[1,3]thiazolo[3',2':2,3][1,2,4]triazino-[5,6-b]indole, at N-10.
