Recognized for its reactivity, NAM copolymerizes with many different monomers and the synthesized materials, like all the materials derived from disubstituted
acrylamides, are characterized by solubility in a wide range of solvents, from aqueous to organic ones.
Some authors also have reported that the kinetic diffusion of the less-stable disubstituted
anthocyanins is faster than that of the trisubstituted ones.
99% of which is 2-6 disubstituted
piperidines, which have haemolytic, antibacterial, insecticidal and cytotoxic properties.
A recent comparative study of the antioxidant activity of several coumarins showed that 4-methylumbelliferone was completely inactive against liver toxicity induced by carbontetrachloride, whereas other C-6 and C-7 disubstituted
coumarins (esculetin and scoparone) significantly prevented oxidative stress induced by carbon-tetrachloride (Bilgin et al.
Use of Grignard reagents allows for the isolation of monosubstituted and disubstituted
products, whereas use of organolithium reagents allows for the isolation of only the disubstituted
The dienes investigated are benzo[b]thiophene S-oxide, dibenzonthiophene S-oxide, 2-methylbuta-1,3-diene, Danishefky's diene and disubstituted
thiophene S-oxides with electron donating groups, while the dienophiles were 1,2-dicyanoethene, 1,2-dicyanoethyne and disubtituted thiophene S-oxide with electron withdrawing groups (Fig.
2]O) was found to be effective in the synthesis of cis-isoquinolic acids [16a], mono- and disubstituted
2,3-dihydroquinazolin-4(1H)-ones [16b], dihydropyrimidines via Biginelli reaction [16c], coumarins [16d], 1,3,4- oxadiazoles [16e], dibenzoxanthenes [16f], 1,5-benzodiazepines [16g], trisubstituted imidazoles [16h], mono and bis(spiro-2-amino-4H pyran)[16i] etc.
Suppression of adult emergence of treated eggs of Tribolium castaneum Herbst by new synthesized disubstituted
benzoylphenyl urea compounds.
A polymerization process comprising contacting one or more monomer(s), wherein the one or more monomer(s) is independently selected from the group consisting of olefins, alpha-olefins, disubstituted
olefins, isoolefins, conjugated dienes, non-conjugated dienes, styrenics, substituted styrenics and vinyl ethers, one or more Lewis acid(s), and a diluent comprising one or more hydrofluorocarbon(s) (HFC's) in a reactor and wherein the diluent comprises from 15 to 100 volume % HFC based upon the total volume of diluent, the temperature of the polymerization is less than 0[degrees]C and the pressure is from above 0 to 14,000 kPa and wherein the one or more Lewis acid(s) is represented by the formula [MR.
