Bajaj, Asymmetric Allylation of Sulfonyl Imines
Catalyzed by in Situ Generated Cu (II) Complexes of Chiral Amino Alcohol Based Schiff Bases, Rsc Adv., 4, 56424 (2014).
In IR spectra of corresponding product display the absence of characteristic absorption band near 1580-1590 [cm.sup.-1] due to C=N stretching of imines
and appearances of 1670 [cm.sup.-1] of C=O stretch indicate the formation of four membered [beta]-lactum ring.
Herein, with the aim of obtaining multifunctional photoand ionochromic and fluorescent compounds, we report the synthesis of novel 5-phenylpyrazolidin-3-one-based azomethine imines
containing 2-((1H-imidazol-2-yl)methylene) 1, 2-(pyridin-2-ylmethylene) 2, 2-(quinolin-2-ylmethylene) 3, and2-((8-hydroxyquinolin-2-yl)methylene) 4 substituents and the investigation of their photochromic, fluorescent, and chemosensor properties.
Aziridine 2-methyl- is an imine
which is widely spread in ten sampling stations out of thirteen (Table 7).
Peaks observed in the regions 159.27-159.29 and 160.48-162.49 ppm are due to imines
and urethane carbonyl carbons, respectively (30).

In the presence of tin(II) chloride, bromonitromethane reacts with imines
derived from aromatic aldehydes and ammonia to yield 2-amino-2-aromatic substituted nitroethane derivatives via an addition reaction in good yields .
It has been reported elsewhere that primary amines produce imines
on reaction with aldehydes and ketones, although ketones react more slowly than aldehydes, sometimes requiring higher temperatures and longer reaction times.
Furthermore, for reduction, gold can hydrogenate alkenes, alkynes, imines
and carbonyls in the presence of H2.
Alkylation of ketones and imines
, asymmetric allylic alkylation, phase-transfer catalysis, radical reactions and enzymatic methods.
Today, there are a variety of LMW and HCD coagulants on the market, from polyamides and polyamines, to polyethylene imines
, alum, ferric chloride and so on.
