Pyridine-2-carbaldehyde, also called 2-formylpyridine, is an organic compound with the formula NC 5 H 4 CHO. It is one of three isomeric pyridinaldehydes. The other isomers are pyridine-3-carboxaldehyde and pyridine-4-carboxaldehyde. Pyridine-2-carbaldehyde is a colorless oily liquid with a distinctive odor.
N-Formylpiperidine is an organic compound with the formula C 6 H 11 NO. It is the amide of formic acid and piperidine.It can be used as a polar aprotic solvent, with better hydrocarbon solubility than other amide solvents such as dimethylformamide (DMF). [1]
4-Pyridone is an organic compound with the formula C 5 H 4 NH(O). It is a colorless solid. Preparation. 4-Pyridone, and its derivatives, are prepared from 4-pyrone ...
Pyridine and poly(4-vinyl) pyridine have been shown to form conducting molecular wires with remarkable polyenimine structure on UV irradiation, a process which accounts for at least some of the visible light absorption by aged pyridine samples. These wires have been theoretically predicted to be both highly efficient electron donors and ...
Formyl functional group is shown in blue. Formylation refers to any chemical processes in which a compound is functionalized with a formyl group (-CH=O). In organic chemistry, the term is most commonly used with regards to aromatic compounds (for example the conversion of benzene to benzaldehyde in the Gattermann–Koch reaction).
Pyridine-4-carbaldehyde is an organic compound with the formula C 5 H 4 NCHO. It is one of three isomeric pyridinaldehydes. The other isomers are pyridine-2-carboxaldehyde and pyridine-3-carboxaldehyde. Pyridine-4-carboxaldehyde is a colorless liquid, although aged samples can appear yellow or even brown.
The Bouveault aldehyde synthesis (also known as the Bouveault reaction) is a one-pot substitution reaction that replaces an alkyl or aryl halide with a formyl group using a N,N-disubstituted formamide. [1] [2] For primary alkyl halides this produces the homologous aldehyde one carbon longer. For aryl halides this produces the corresponding ...
4-Pyrrolidinylpyridine is an organic compound with the formula (CH 2) 4 NC 5 H 4 N. The molecule consists of a pyrrodinyl group ((CH 2) 4 N-) attached via N to the 4-position of pyridine. It is a white solid. The compound has attracted interest because it (pK a = 9.58) is more basic than dimethylaminopyridine (pK a = 9.41). [1] It is a popular ...
