Ring Transformation of Heterocycles Transformation of 4, 5-Dihydro-5, 5-Dimethyl-H-1, 2, 4-Triazoles Into 5-Methyl-H-1, 2, 4-Triazoles

, 2001
Reaction of 1-aryl-3-acetyl-4, 5-dihydro-5, 5-dimethyl-1H-1, 2, 4-triazoles (3) with acetyl chloride or acetic anhydride is found to give the ring transformation product 1-aryl-3-acetyl-5-methyl-1H-1, 2, 4-triazoles (4) instead of the expected N-acetyl derivative (5). This ring transformation is believed to start with N-acylation of the dihydrotriazole

Synthesis of 1, 2, 4- Triazole Derivatives And Their Biological Activity Study

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
This study includes the synthesis of new derivatives of 1, 2, 4- Triazole which are contain Schiff bases derived from 1, 4, 5, 6- tetrahydropyrimidine. The structures of these derivatives were characterized from their melting points, infrared spectroscopy and elemental analysis.

Precise Tailoring of the Coordination Environment of Single‐Atom Cu(I) on Trifurcate AlL3 Supports for Click Chemistry

Rare Metals, EarlyView.
ABSTRACT Single‐atom catalysis hinges on fundamental challenges in precisely controlling metal‐support interactions and rationally regulating metal–adsorbate relationships. Herein, we report a universal strategy for constructing highly efficient and well‐defined Cu(I) single‐atom catalysts based on a trifurcate AlL3 molecular support.

Combining Laser‐Induced Edition to Collision‐Induced Sequencing of Digital Oligomers in a Single Gas‐Phase Experiment

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale To increase the confidentiality level of molecular tags, binary information can be hidden in sequence‐defined oligomers using isobaric monomers including a photo‐sensitive one, which mass can be modified upon light irradiation. Reading such secured data requires light edition prior to MS/MS sequencing, which was investigated here in ...
