Abstract
The reaction of substituted 3-chloro-1,2,4-triazino[2,3-f]theophyllins with secondary amines gives new water-soluble active media for dye lasers. The luminescence and generation characteristics of these compounds were studied. These properties were found to depend on the lactam-lactim tautomerism of 1,2,4-triazino[2,3-f]theophyllin-4H-3-ones.
