The compound 6 bearing 3,5-dibromo-4-hydroxyphenyl and compound 12 p-methyl phenyl substituents
showed potent activity (9.
Specifically, indoles possessing a variety of electronically different substituents
, including halogen, alkyl, alkoxy, cyano and methoxy carbonyl groups at different positions on the bezene ring undergo reaction to produce the corre-sponding substituted tertiary alcohol in good to ex-cellent yields (Table 2, compounds 4, 5, 7-12, 14, 16-21).
have been implemented in cobalt ferrites to investigate the electrical and magnetic properties so as to identify the variations in its characteristics [9-10].
Objective: Enantiopure quaternary amino acids, carrying two carbon-based substituents
at the a carbon, are one of the most important groups of modified a amino acids, of great commercial value in the development of new pharmaceuticals and agrochemicals.
P-Xylene is an aromatic hydrocarbon based on benzene with two methyl substituents
with the chemical formula C₈H₁₀ or C₆H₄(CH₃)₂.
Applications of viologens  cannot be limited to its short alkyl group substituents
In other words, differences in the birefringence properties of PPFPhMA, PPhMA, and PTFEMA as compared to PMMA are caused by the contributions of the substituents
on each polymer.
We also evaluated cellulose tribenzoate derivatives with various substituents
on the phenyl groups, and found that tris(4-methylbenzoate) showed a much better chiral recognition than cellulose tribenzoate to many racemates.
Hypothesis: The reaction conducted on benzaldehydes with electron-donating substituents
may result in even larger shifts towards the products of the secondary and tertiary Leuckart reactions.
The structure of the side-chain substituents
on the polymer backbone is a major compositional factor, impacting polymer functionality.
Cyclobutane is condensed to aromatic rings such as benzene, naphthalene, anthracene, and pyrene and may have different substituents
such as alkyl, alkoxy, alkylthio, and aryl groups.
The results suggest that alkyl substituents
lead to the rccc conformation while aryl substituents
would lead to the rctt conformation.
