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

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.

A Convenient Synthesis of 1,5-Fused 1,2,4-Triazoles from N-Arylamidines via Chloramine-T Mediated Intramolecular Oxidative N-N Bond Formation

A convenient synthesis of 1,5-fused 1,2,4-triazoles from readily available N-arylamidines is reported. The reaction is efficiently promoted by chloramine-T to afford the desired products mostly in high yields and in relatively short time, through direct m

I2/KI-Mediated Oxidative N-N Bond Formation for the Synthesis of 1,5-Fused 1,2,4-Triazoles from N -Aryl Amidines

An I2/KI-mediated oxidative N-N bond formation reaction is described. This new and environmentally benign approach allows for the convenient synthesis of a variety of 1,2,4-triazolo[1,5-a]pyridines and other 1,5-fused 1,2,4-triazoles from readi
