The cycloaddition reaction of some arylazides to enamines 4a-f afforded v-triazolines 5a-i; by subsequent acid-catalyzed hydrolysis v-triazoles 6a-c were obtained. The reversibility of the cycloaddition was demonstrated on the basis of spectroscopic or chemical evidences.
某些芳基
叠氮化物与烯胺4a-f的环加成反应得到v-三唑啉5a-i;m / z为1 。通过随后的酸催化
水解,得到v-三唑6a-c。根据光谱或
化学证据证明了环加成反应的可逆性。
