  Synthesis, photophysical and redox properties of the 2,5,7-tri(het)aryl-[1,2,4]triazolo[1,5-a]pyrimidines

  摘要：

  A number of Y-type push-pull compounds based on the [1,2,4]triazolo[1,5-a]pyrimidine core, namely 5,7-di(het)aryl-substituted 2-phenyl-[1,2,4]triazolo[1,5-a]pyrimidines, were obtained by transition metal free nucleophilic C-H functionalization. Substituents at both the C-5 and C-7 positions were introduced by successive treatment of the starting 6-bromo-2-phenyl-[1,2,4]triazolo[1,5-a]pyrimidine with Grignard reagents. In addition, the optical and electrochemical properties of the synthesized push-pull systems were studied.[GRAPHICS].

  A new protocol for the palladium-catalyzed C−H arylation of pyrazolo[1,5-a]azines, using low-cost and abundant (hetero)aryl chlorides as the coupling partners, and without any stoichiometric metal additives is reported. The structural motif of coupling products can be found in many drugs and organic materials.
