✦ Synopsis


Low-temperature (100 K) x-ray diffraction studies and ab initio calculations show significant localization of the -electron structure in 2,4,6-trimethoxy-s-triazine. Possible rationalizations for this observation are discussed.

The ionization (or basicity) constants (pK b ) were determined for many 2-substituted 4,6-diamino-s-triazines (I) by means of the electrometric titration. I includes 2-alkoxy or aryloxy-(Ia), 2-alkyl-or 2-aryl-(Ib), and 2-alkylamino-or 2-arylamino-4,6-diamino-s-triazines (Ic). For the series with th
