2-Pyrrolidone, also known as 2-pyrrolidinone or butyrolactam, is an organic compound consisting of a 5-membered lactam, making it the simplest γ-lactam. It is a colorless liquid that is miscible with water and most common organic solvents.
Pyrrolidine, also known as tetrahydropyrrole, is an organic compound with the molecular formula (CH 2) 4 NH. It is a cyclic secondary amine , also classified as a saturated heterocycle . It is a colourless liquid that is miscible with water and most organic solvents.
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).
Subsequently, Formyl peptide receptor 2 and Formyl peptide receptor 3 were also cloned based on the similarities in their amino acid sequence to that of formyl peptide receptor 1. Formyl peptide receptors 2 and 3 have very different abilities to bind and respond to formylated oligopeptides including fMLF compared to formyl peptide receptor 1 ...
The lolines may be neurotoxic to the insects, and differences in the chemical groups at the C-1-amine result in different levels of insect toxicity; for example, N-formylloline (see Fig. 2), which occurs in higher concentrations in endophyte-infected grass plants, [7] has greater insect toxicity than some other lolines, which occur at lower ...
N-Vinylpyrrolidone (NVP) is an organic compound consisting of a 5-membered lactam ring linked to a (2 carbon) vinyl group. It is a colorless liquid although commercial samples can appear yellowish. It is produced industrially by vinylation of 2-pyrrolidone, i.e. the base-catalyzed reaction with acetylene. [2]
CROP proceeds through an S N 1 or S N 2 propagation, chain-growth process. [20] The mechanism is affected by the stability of the resulting cationic species. For example, if the atom bearing the positive charge is stabilized by electron-donating groups , polymerization will proceed by the S N 1 mechanism. [ 21 ]
This electrophile attacks the C-2 carbon of an unoxidized molecule of pyrrole to give a dimeric cation [(C 4 H 4 NH) 2] ++. The process repeats itself many times. Conductive forms of PPy are prepared by oxidation ("p-doping") of the polymer: (C 4 H 2 NH) n + 0.2 X → [(C 4 H 2 NH) n X 0.2] The polymerization and p-doping can also be effected ...
