There are signals belonging to the aromatic substituent on the amide group and three more at 8.54 to 8.06 ppm, 8.34 to 7.95 ppm, and 7.87 to 6.70 ppm for aromatic benzophenone core.
In addition to hydrogen bonding to the obvious ammonium group of the bicyclic amine, the McBreen study has shown that binding between the aromatic hydrogens of the adsorbed aromatic substituent and the carbonyl oxygen also occurs.
The relative effect of an aromatic substituent at the 2-position is as significant as the nature of a fused ring (Table 1).
Overall the molecules 5a, 5b and 5c bearing the small aliphatic chains remained much efficient as compared to others and also bromo aromatic substituent. The halogen bearing molecules are known to possess better biological activities [13].
In addition, the2,4-diamino-6-R-1,3,5-s-triazines (R phenyl,4-pyridyl) include an aromatic substituent in position6 of the triazine ring, which plays a crucial role in the formation of p-p stacking interactions and the structure of new compounds.
Surprisingly, the results showed that both aliphatic and aromatic substituents had no significant effect on the reaction times and the yields (Table-3, entries 1-5).
(25) Aromatic substituents on expanded porphyrins such as hexaphyrin can be also borylated.
As discussed previously, bulky conjugated or aromatic substituents have a high refractive index.
Synthesis of hydrazines with aromatic substituents using triarylbismuth reagents.
Effects of aromatic substituents on the photocleavage of 1-acyl-7-nitroindolines.
The acidolysis reaction should also produce carboxylic acid with aromatic substituents, Ar-COOH, and if the [COO.sup.-] [Na.sup.+] salt groups from the EAA-Na participate in the acidolysis reaction, aromatic carboxylate salts, Ar-[COO.sup.-] [Na.sup.+], may also be formed.
The mechanism of thermal degradation of poly[bis(phenoxy)phosphazene] involves depolymerization to the cyclic trimer, followed by crosslinking of these trimers through condensation of the aromatic substituents. Volatilization of uncrosslinked timers accounts for the dramatic weight loss at 400[degrees]C.
