N-N-Dimethylformamide was determined every hour during the eight hours of the work shift in the alveolar air of eight workers employed in an artificial leather factory and in the breathing zone of the eight workers. The alveolar ventilation of each worker was measured for 10 minutes during the work shift. Alveolar dimethylformamide concentration (Ca) was correlated with the environmental concen...

Dimethylformamide dimethylacetal (DMFDMA) is widely used as a source of electrophilic one-carbon units at the formate oxidation level; however, electrophilic methylation with this reagent is previously unreported. Reaction of anthranilamide with DMFDMA at 150 °C for short periods gives mainly quinazolin-4-one. However, prolonged reaction with dimethylformamide di(primary-alkyl)acetals leads to ...

A new N-protecting group, ethanesulfonylethoxycarbonyl (Esc), was designed to perform peptide synthesis in both aqueous and organic solvents. Esc-amino acids were prepared by the reaction of Esc-Cl and amino acids. Although Esc-Cl was a highly reactive reagent, it was not stable and decomposed during the purification procedure. A more stable reagent, ethanesulfonylethyl-4-nitrophenyl carbonate ...

The solid-state structure of the complex para-sulphonato-calix[8]arene – dimethylammonium – dimethylformamide shows the para-sulphonato-calix[8]arene anion in a pleated cone conformation with the inclusion of four dimethylammonium cations and the dimethylformamide positioned exo to the macrocycle.

Reaction of 3-aminobenzenesulfonic acid (HL1) with Cu(NO3)2·2.5H2O in H2O/DMF leads to the formation new bis(3-aminobenzenesulfonato-κN)-diaqua-bis(dimethylformamide-κO)-copper(II) complex [Cu(L1)2(DMF)2(H2O)2] (1) (HL1 = and DMF N,N-dimethylformamide). Single crystal X-ray analysis reveals that hexacoordinated copper(II) center adopts a distorted octahedral geometry trans-oriented two 3-aminob...

Facial flushing and other symptoms were reported by 19 of a group of 102 men who worked with dimethylformamide (DMF). Twenty-six of the 34 episodes occurred after the workers had consumed alcoholic drinks. The metabolite N-methylformamide (MF) was detected in the urine on 45 occasions, the highest recorded concentration being 77 microliter/litre. The highest recorded concentration of DMF in air...

The boiling point is 1530 C., and it is miscible with water and some organic solvents. On boiling with water or alkali it hydrolyzes to formic acid and dimethylamine. It is more stable than formamide and can be distilled. For the present work freshly distilled dimethylformamide was used and all aqueous solutions were freshly prepared. Dimethylformamide in the atmosphere may be trapped by passin...
