GENERAL
DESCRIPTION & APPLICATIONS
|
Imidazolidine is the hydrogen-saturated analogue of imidazole
and imidazoline dihydrogenated one. Imidazoline has
a single double bond but imidazolidine has no double
bond. The resonance structures of
imidazole keep the aromaticity intact. Imidazole is a base and an excellent nucleophile. It reacts at the NH nitrogen.
Generaly nucleophilic substitutions at the carbon atoms
except C-2 are
difficult with imidazole. But It is susceptible to electrophilic attacks at the carbon atoms
with imidazoline and imidazolidine. Imidazoline
molecules are sympathomimetic agents effecting on alpha-adrenergic
receptors primarily
and little effecting on
beta-adrenergic receptors. The imidazoline derivatives
of adrenergic alpha-agonist include
oxymetazoline
(CAS
RN: 1491-59-4)
, xylometazoline (CAS
RN: 526-36-3), tetrahydrozoline
(CAS
RN: 84-22-0) , and naphazoline (CAS
RN: 835-31-4), They are found in topical ophthalmic and nasal decongestants. Imidazoline
and imidazolidine derivatives acts as a chain
extender in polymerization process and can form thermally stable
polymeric products. Protonated adducts can be used as a curing agent and in
aqueous
electrocoating baths.Adducts of imidazolidine compounds are utilized as a heterocyclic
ligand in
transition-metal coordination chemistry. Alkyl imidazolines are used as a microbiocide,
algaecide or fungicide used in fuel and oil. Members
