Abstract
Dihydropyrazines reacted with 1,2-diamines to form tetraazadecalins as inte rmediates, and then the reaction proceeded forward to dissociate into alter nate dihydropyrazine and diamine, or backward to dissociate into the starti ng materials in certain equilibrium. The product distribution is controlled by diamine-exchange equilibrium reaction. The various equilibrium reaction s were analyzed by NMR spectroscopy.
