The Mode of Protonation of Amides [PDF]

, 1958
The relative basicities of oxygen versus nitrogen in amides is a problem which has not been satisfactorily resolved. However, it might be anticipated from considerations of resonance and structural parameters that in strongly acidic solutions the proton ...

An amide cyclophane [PDF]

Acta Crystallographica Section E Structure Reports Online, 2014
The title compound, 8,18-dithia-2,6-diaza-13(1,4)-piperidina-1(1,2),4(1,3),7(1,2)-tribenzenaoctadecaphane-10,15-diyne-3,6-dione, C32H30N4O2S2, is composed of a relatively planar bis(2-mercaptophenyl)isophthalamide unit linked to a bridging 1,4-di(but-2-yn-1-yl)piperazine unit, forming a macrocycle.

Ruthenium-Catalyzed Oxidative Amidation of Alkynes to Amides [PDF]

Organic Letters, 2019
Complex CpRuCl(PPh3)2 catalyzes reactions of terminal alkynes with 4-picoline N-oxide and primary and secondary amines to afford the corresponding amides. The reactions occur in chlorinated solvent and aqueous medium, showing applications in peptide chemistry.

Water-stable plasma-polymerized N,N-dimethylacrylamide coatings to control cellular adhesion [PDF]

, 2020
The plasma polymerization of amide-based precursors is a nearly unexplored research area, which is in contrast with the abundance of reports focusing on amide based surface modification using wet chemistry.

para-Selective C-H amidation of simple arenes with nitriles [PDF]

, 2015
A para-selective C-H amidation of simple arenes with nitriles has been developed. By increasing the amount of arenes, a further meta-selective C-H arylation of the produced amides occurred.

Nickel-catalyzed transamidation of aliphatic amide derivatives. [PDF]

, 2017
Transamidation, or the conversion of one amide to another, is a long-standing challenge in organic synthesis. Although notable progress has been made in the transamidation of primary amides, the transamidation of secondary amides has remained ...

Metabolism of amino acid amides in Pseudomonas putida ATCC 12633 [PDF]

, 1993
The metabolism of the natural amino acid L-valine, the unnatural amino acids D-valine, and D-, L-phenylglycine (D-, L-PG), and the unnatural amino acid amides D-, L-phenylglycine amide (D, L-PG-NH2) and L-valine amide (L-Val-NH2) was studied in ...

A two-step approach to achieve secondary amide transamidation enabled by nickel catalysis. [PDF]

, 2016
A long-standing challenge in synthetic chemistry is the development of the transamidation reaction. This process, which involves the conversion of one amide to another, is typically plagued by unfavourable kinetic and thermodynamic factors. Although some

2-Diphenylphosphanyl-4-pyridyl(dimethyl) amine as an effective ligand for the ruthenium(II) complex catalyzed homogeneous hydration of nitriles under neutral conditions [PDF]

, 2011
New homogeneous catalyst comprised of [Ru(methallyl)(2)(cod)] (cod = 1,5-cyclooctadiene) (1) and 2-diphenylphosphanyl-4-pyridyl(dimethyl) amine (2) is shown to efficiently catalyze the hydration of various nitriles under neutral conditions. The hydration
