, p. 11733 - 11735 (2012)
Hydrotalcite-supported gold nanoparticles (Au/HT) catalyzed the highly efficient double-carbonylation of amines to oxamides under mild reaction conditions. Various amines were selectively converted to the corresponding oxamides. The cooperation between gold nanoparticles and basic sites of HT plays a key role in the reaction.
Vibrational characterization of the tertiary amide and thioamide group.
Desseyn,Herrebout,Clou
, p. 835 - 849 (2003)
Force field calculations and vibrational spectra of (CH(3))(2)NCOCON(CH(3))(2) (TMO), (CH(3))(2)NCOCSN(CH(3))(2) (TMMTO) and (CH(3))(2)NCSCSN(CH(3))(2) (TMDTO) are discussed. The amide and thioamide fundamentals and those of other simple tertiary amides are compared. A characteristic pattern in infrared and Raman is proposed.

The present invention provide a process for the production of compounds of general formula (I), Y-CH2CH2-Z (I) wherein Y and Z are functional groups independently selected from the group consisting of a hydroxyl group and R1R2N and wherein R1 and R2 may be the same or different and are functional groups selected from the group consisting of hydrogen and substituted or non- substituited alkyl groups comprising 1 to 8 carbon atoms, or R1R2N is a cyclic compound selected from the group of aromatic and non-aromatic cyclic compounds optionally comprising one or more heteroatoms in addition to the nitrogen atom, said process comprising the steps of: (i) reacting carbon monoxide and an amine in the presence of oxygen to provide a compound of general formula (II) wherein R1 and R2 or R1R2N are as defined above and X is selected from the group consisting of R1R2N and R3O, wherein R3 is selected from alkyl groups comprising 1 to 8 carbon atoms; and (ii) converting the compound of general formula (II) into a compound of general formula (I) by a process that comprises a hydrogenation reaction.
A FACILE, CONVENIENT AND SELECTIVE HOMOLYTIC CARBAMOYLATION OF HETEROAROMATIC BASES
Coppa, Fausta,Fontana, Francesca,Lazzarini, Edoardo,Minisci, Francesco
, p. 2687 - 2696 (2007/10/02)
The oxidative decarboxylation of monoamides of oxalic acid provides carbamoyl radicals, which are useful for the selective carbamoylation of protonated heteroaromatic bases; this reaction represents the first general and selective method for the N-alkyl or N-arylcarbamoylation of heteroaromatic bases.Compared to alkoxycarbonylation, this reaction is much more effective and selective, owing to more favourable polar and enthalpic effects.The importance of the steric effects is also emphasized.
Oxidative coupling of amines and carbon monoxide catalyzed by palladium complexes. Mono- and double carbonylation reactions promoted by iodine compounds.

, p. 1544 - 1547 (2007/10/02)
Iodine is an effective promoter for the carbonylation of primary and secondary amines to ureas using palladium acetate as the catalyst and a base (e.g.K2CO3) in acetonitrile (3 h at 95 deg C and 2.7 atm).Oxamides are formed in excellent yields when secondary amines are carbonylated in the presence of iodide ion and oxygen, while primary amines give ureas as the principal product at 95 deg C, and oxamide at room temperature.
Radical Production evidenced by Dimer Analysis in γ-Irradiated Amides in Aqueous Solutions and in the Solid State
Dusaucy, Anne-Catherine,Doncker, Joelle De,Couillard, Christine,Leat, Marc De,Tilquin, Bernard
, p. 125 - 134 (2007/10/02)
A study of the nature and distribution of radicals produced by the radiolysis of amides in the solid state has been made by two complemetary methods: (i) final product analysis by capillary gas chromatography and (ii) the direct observation of radicals by electron spin resonance spectroscopy.The dimer isomer distribution for N-methylformamide (NMF), N-methylacetamide (NMA) and N,N-dimethylformamide (DMF) allows one to estimate the parent radical distribution by using a statistical rule for dimer formation.In the solid state the radiolytic formation of radicals is selective.Final product analysis by capillary gas chromatography and the direct study of radicals by pulse radiolysis are also complemetary methods for studying the nature of radicals produced from the radiolysis of amides in aqueous solutions.The selective production of one parent radical is characteristic of dilute solutions.
