説明

It was clarified that 3-cyano-2-methyl-1-phenylisothiourea (1) reacted with silver nitrate in the presence of triethylamine to give rise to N-cyano-N'-phenylcarbodiimide (2), which reacted with 1 to give 2-cyanoimino-4-[(N2-cyano-An-phenylamidino)imino]-6-methylthio-1, 3-dipheny1-1, 2, 3, 4tetrahydro-1, 3, 5-triazine (3). In a similar manner, compound 1 reacted with two molar amounts of phenyl isocyanate, phenyl isothiocyanate and diphenylcarbodiimide in the presence of triethylamine to afford corresponding tetrahydro-1, 3, 5-triazines 11, 12 and 13 respectively.
