Hammett constants correlate very well with thechanges in BDE, IP and PA values in the case of anilines, phenols, chromans and thiophenols
Copper iodide nanostructure has numerous applications, including its application as a catalyst in the synthesis of phenol, aniline, and thiophenols
from aryl halides in aqueous solutions.
Reaction of compound 1 with different para-substituted phenols (2, X = O, [R.sub.2] = H, Cl, Br or N[O.sub.2]) anilines (2, X = NH, [R.sub.2] = H, Cl, Br or N[O.sub.2]) thiophenols
(2, X = S, [R.sub.2] = H or Cl) resulted phenoxy derivatives (3a-t), anilino derivatives (4a-h) and thiophenoxy derivatives (5a-d) where as reaction of 1 (n = 1-4) with 2-amino pyridine (6) resulted compounds (7a-c) (Scheme 1).
The free radicals rapidly react with oxygen or any radical acceptor or peptizer (such as thiophenols
or aromatic disulfides).
, aromatic disulfides and chelate complexes of iron, cobalt, copper and manganese catalyze the thermo-oxidative characteristics of some elastomers.
In conclusion, in this work, we have developed efficient synthetic approaches to a series of novel 6-(arylthio)-1,3dioxepan-5-ols starting from 1,3-dioxacyclohept-5-ene through its oxidation followed by thiolysis with various thiophenols
. Depending on the reaction conditions, this process can theoretically lead to the corresponding isomeric five-, six-, and seven-membered cyclic acetals: 1,3-dioxolanes, 1,3-dioxanes, and 1,3-dioxepanes, respectively.
Rubber broken down in this manner usually will have a higher tear strength and resilience than rubber broken down by chemical peptizers such as thiophenols
. Fatty acids and fatty acid soaps have a limited solubility in rubber compounds.
