Abstract:
The reaction of N,N-diaryl-substituted formamides with oxalyl chloride gives rise, instead to the formation of the expected salt-like formamide chlorides, to the formation of corresponding non-ionic N-dichloromethyl-substituted diarylamines.

Abstract:
Hydroamidation of olefins with N-substituted formamides is performed with dodecacarbonyltriruthenium (Ru3(CO)12) at 180°C under N2 or CO atmosphere in toluene and in a series of ionic liquids. Yields of 99% with 94–97% exo selectivity are found in the addition of N-methylformamide to 2-norbornene under CO both in toluene and in the ionic liquid 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [bmim][NTf2]. The presence of CO or a phosphine is necessary for significant reaction to occur, with CO more effective than triphenylphosphine in all ionic liquids investigated. Reasonable yi

Abstract:
Context. Many complex organic molecules (COMs) observed in the interstellar medium (ISM) are probably not formed in the gas phase. A large consensus has developed that it could be related to the icy surfaces in this environment. Aims. We investigate the process of building N-substituted formamides in the ISM by successive additions of atomic hydrogen to isocyanates. The key point is to see whether the pre-adsorption of the atomic hydrogen on the ice surface is a driving vector as it is for the formation of CH3OH from CO. Methods. We use quantum numerical simulations, namely density functional

Abstract:
A short and economical synthesis of various 2-methylaminopyidine amides (MAPA) from 2-bromopyridine has been developed using the catalytic Goldberg reaction. The effective catalyst was formed in situ by the reaction of CuI and 1,10-phenanthroline in a 1/1 ratio with a final loading of 0.5–3 mol%. The process affords high yields and can accommodate multigram-scale reactions. A modification of this method provides a new preparation of 2-N-substituted aminopyridines from various secondary N-alkyl(aryl)formamides and 2-bromopyridine. The intermediate aminopyridine formamide is cleaved in situ thro

Abstract:
Pyridines and benzopyridines substituted with trimethylsilylmethyl groups, α or γ to the nitrogen atom, have been found to react with formamides by way of a Peterson reaction to form enamines. Trimethylsilylmethylbenzene behaved similarly. The enamines prepared from Nb-formyl-Na,Nb-dimethyltryptamine cyclized readily to β-carbolines. The reaction of formamides with lithiated 4-methylpyridines as a route to enamines was examined but proved to be less general and proceeded in lower yield than the route by way of the Peterson reaction.

Abstract:
The reaction between the formamidine ligand PriN=CHNHPri and the activated cluster Os3(CO)10(MeCN)2 has been studied. A rapid reaction is observed at room temperature, yielding the hydride clusters HOs3(CO)9[&#956;-OCNPriC(H)NPri] and HOs3(CO)10[&#956;-NPriC(H)NPri] as the principal products. The spectroscopic data and X-ray diffraction structures of those formamidinate-substituted clusters will be present. The thermal reactivity of the clusters has been investigated, with the face-capped cluster HOs3(CO)9[&#956;-NPriC(H)NPri] found as the sole observable product. The relationship between thes
