Temperature-Dependence of the Amide-I Frequency Map for Peptides and Proteins
Amide-I Frequency map Infrared spectrum Molecular dynamics simulation
2012/4/5
In our recent work [Phys. Chem. Chem. Phys. 11, 9149 (2009)], a molecular-mechanics force field-based amide-I vibration frequency map (MM-map) for peptides and proteins was constructed. In this work, ...
Proposal of an Amide-Directed Carbocupration Mechanism for Copper-Catalyzed meta-Selective C-H Arylation of Acetanilides by Diaryliodonium Salts
C bond activation Carbocupration Copper catalysis Density functional theory Selectivity
2012/4/5
We examined the puzzling mechanism for Cu-catalyzed meta-C-H arylation reaction of anilides by diaryliodonium salts through systematic theoretical analysis. The previously proposed anti-oxy-cupration ...
Spectroscopic studies and Hartree-Fock ab initio calculations of a substituted amide of pyrazine-2-carboxylic acid - C16H18ClN3O
Amides of pyrazine carboxylic acid IR Hartree-Fock ab initio calculations, hyperpolaziability
2010/4/8
A substituted amide of pyrazine-2-carboxylic acid was prepared and the IR spectrum was recorded and analysed. The compound prepared was identified by NMR and mass spectra. The vibrational frequencies ...
Rapid Synthesis of New Poly(amide-imide)s Based on N-(4-Carboxy phenyl) trimellitimide and Hydantoin Derivatives under Microwave Irradiation
Thermally stable polymers icrowave irradiation Poly (amide-imide Hydantoin derivatives
2010/4/9
Six new poly (amide-imide)s (6a-f) were prepared under microwave irradiation by polycondensation reaction of diacid chloride (4) with 6 different derivatives of hydantoins (5a-f) using O-cresol as a m...
