Abstract: | The reduction of trichloromethyl groups in sym-triazine derivatives to methyl groups is studied. It is shown that 2-R-4, 6-bis (trichloromethyl)-sym-triazines can be reduced to 2-R-4, 6-dirnethyl-sym-triazines with zinc dust in ethanol or with lithium aluminum hydride in THF. 2-Amino, N-substituted 2-amino-, and 2-alkoxy-4-trichloromethyl-6-R-sym-triazines are reduced to the corresponding methyl derivatives by boiling with lithium aluminum hydride in dibutyl ether.I.
