What is an amide vs Amine? An amide differs from an amine in both its structure and properties. An amide consists of an acyl group attached to the NH2 group, while an amine consists of an alkyl group attached to NH2. Amides are comparatively less basic than amines, because the lone pai...

It is purified by refluxing over Na wire or NaH for 30minutes and then distilled into a receiver under N2. Because of the low boiling point of the amine, a dispersion of NaH in mineral oil can be used directly in this purification without prior removal of the oil. It is HIGHLY FLAMMABL...
Progress of the reaction was measured by fluorescence detection of 6-methoxypyridin-3-amine at an excitation wavelength of 303 nm and an emission wavelength of 394 nm at 37 °C by the use of a microplate reader (Molecular Devices., CA, USA). The substrate, OMP, was synthesized following ...
To the flask was fitted, a reflux condenser was made, and then THF (20 ml) and bis(trimethylsi1yl)amine (3.81 ml, 18.1 mmol) were added. The resultant slurry was sonicated until the hydrogen gas evolution had ceased, and almost all the potassium hydride had been consumed (3.25 h). ...

To resolve these issues we considered smaller and hence computationally less demanding nitramine compounds, including nitramide [34], dimethylnitramine [34] (DMNA) and 1,3-dimethyl-1,3-dinitro methyldiamine (DDMD) [35] (see Fig 1). Despite their relatively small size and simple structure, ...
