5,6-Dihydro-2,4(1H,3H)-pyrimidinediones underwent dehydrogenation at the 5- and 6-position producing 2,4(1H,3H)-pyrimidinediones in aqueous solution induced by argon arc plasma or flames.From consideration based on the kinetic study of this reaction, it was found that abstraction of a hydrogen atom took place preferentially at the 6-position of the dihydropyrimidinediones.
