Abstract
Phenyl (1,3,5-triazin-2-yl)carbamates of the formula (I): ##STR1## wherein R.sup.1 is H, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy, R.sup.2 and R.sup.3 are independently H, halogen atom, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkylthio, C.sub.1 -C.sub.4 haloalkyl, C.sub.1 -C.sub.4 haloalkoxy, C.sub.1 -C.sub.4 haloalkylthio, C.sub.2 -C.sub.4 alkoxyalkyl or NR.sup.7 R.sup.8 (R.sup.7, R.sup.8 : H or C.sub.1 -C.sub.4 alkyl, independently), and R.sup.4, R.sup.5 and R.sup.6 are independently H, halogen atom, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy, are prepared by reacting a 2-amino-1,3,5-triazine of the formula (II): ##STR2## with a diphenyl carbonate of the formula (III): ##STR3## in the presence of an alkali metal hydride in an acrotic polar solvent. An parotic polar solvent mixture of the phenyl (1,3,5-triazin-2-yl)carbamate of the formula (I) and an alkali metal phenoxide is also disclosed.
