The results reveal that all these species have a rigid planar structure and a conjugation system over the tricyclic ring, which is beneficial to their stabilities. The molecular electrostatic potential analysis for all the species shows that the central region of the ring has a very strong ...
ring closure reactionsThe reaction of azoles (I) with trichloroacetonitrile (II) proceeds smoothly and regioselectively at the primary amino group of (I) to yield the trichloroacetamidines (III).doi:10.1002/chin.201306133Kalinin, Dmitrii V....
The s-triazine structure with strong electron withdrawing effect reduced the nucleophilicity of pyridine-like nitrogen atom of imidazole ring, resulting in the suppression of reactivity of the modified imidazole derivatives towards EP at room temperature. Nevertheless, the s-triazine based tri-imidazole ...

The tri-s-triazine terminal-linked ionic liquids so prepared possess multiple functionalities of hydrogen bond donor ability, nucleophilicity, and Lewis base property, which are vital to the ring-opening of epoxide and the activation of CO2. Reaction parameters (temperature, CO2pressure, catalyst ...
Triazine derivatives of the formula: [(NCO)3R1R2R3]n (I) are described, wherein: R1, R2 and R3 are the same or different and represent a ring perhalogenated benzyl and/or xylilydene, and which are bonded to the triazine ring on the N atoms when the ring is saturated, or on the ...
the Cu3 is hexa-coordinated with CuN2O4coordination environment. The organic ligand is coordinated to Cu3 via two nitrogen atoms; one from thes-triazine ring with long Cu3–N5 distance of 2.730(3) Å and the other from the negatively charged N-site from the de-protonated hydrazone NH gro...
