| Abstract: | The ene-like reaction of naphtalen-1-ylamine and naphtalen-2-ylamine, and pyridin-2-ylamine with diethyl azodicarboxylate (DEAD) as well as that of naphthalen-2-ol with 4-phenyl-1,2,4-trizoline-3,5-dione is catalyzed by lithium perchlorate. Also conversion of ester function of (DEAD) to amide function in reaction with 2-aminopyridine and further rearrangement of ethyl N-pyridyn-2-ylcarbamoylazoformate into ethyl pyridin-2-ylcarbamate are catalyzed by LiClO4. |
