Microwave-promoted total synthesis of N-(α-hydroxybenzyl)formamides using DMSO/H2O under neutral conditions

open access: yesGreen Chemistry Letters and Reviews, 2016
A total synthesis route toward N-(α-hydroxybenzyl)formamides by microwave-assisted reaction of dichloroaziridines and aqueous dimethyl sulfoxide is described. The corresponding products were obtained in excellent yields with reduced reaction times.

Identification of the Structure of Triethanolamine Oxygenation Products in Carbon Nitride Photocatalysis

open access: yesChemistryOpen, 2022
Triethanolamine (TEOA) is one of the most commonly used sacrificial agents in photocatalysis. Due to its more complex structure compared to, for example, ethanol, and its sacrificial role in photocatalysis, it gives a mixture of products.

Formamide and the origin of life [PDF]

open access: yesPhysics of Life Reviews, 2012
The complexity of life boils down to the definition: "self-sustained chemical system capable of undergoing Darwinian evolution" (Joyce, 1994) [1]. The term "self-sustained" implies a set of chemical reactions capable of harnessing energy from the environment, using it to carry out programmed anabolic and catabolic functions.

Direct acylation of aryl amines using dimethylformamide and dimethylacetamide as the acyl resources

open access: yesJournal of Saudi Chemical Society, 2016
The treatment of aryl amines with dimethylformamide (DMF) and dimethylacetamide (DMA) in the presence of hydrochloric acid brings about efficient N-acylation to give the corresponding aryl formamides and aryl acetamides in acceptable to excellent yields.
