In the case of oxidative addition-induced reactions, some feasible examples aiming at synthesizing chiral indanes, indolines, dihydrobenzofurans, benzocyclobutenes, and lactams will be developed from readily available aryl or alkenyl halides or triflates.
An alkenyl substituent (1-methylethenyl) resulted in increased antibacterial activity, as seen in limonene [1-methyl-4-(1-methylethenyl)-cydohexene], compared to an alkyl (1-methylethyl) substituent as in p-cymene [l-methyl-4-(1-methylethyl)-benzene].
Medicinal plants are rich in a numerous variety of secondary metabolites of antimicrobial properties such as saponins, tannins, alkaloids, alkenyl phenols, glycoalkaloids, flavonoids, sesquiterpenes lactones, terpenoids and phorbol esters.
The polymer was heated to 175[degrees]C and the alkenyl oxazoline (195 g) was added from the addition funnel over a period of 1 h.
Key statement: A rubber composition comprising (A) an organopolysiloxane end-capped with alkenyldialkylsiloxy, radicals and free of aliphatic unsaturation, (B) an organipolysiloxane containing three alkenyl radicals on molecular side chains, (C) an organohydrogenpolysiloxane, (D) fumed silica and (E) an addition reaction catalyst forms a seal member having improved strength and reduced compression set and useful for sealing a polymer electrolyte fuel-cell separator.
Esters of hydroxycarboxylic acids and alkyl and alkenyl oligoglycosides--such as Cognis' sodium laurylglucoside citrate, sodium laurylglucoside malate, or sodium cocoylglucoside tartrate--are said to permanently re-emulsify silicones, making them easy to remove after each use and preventing buildup.
1995) and later works reporting higher levels of DMA may be attributed to incomplete derivation of alkenyl chains into DMA or differences between the populations.
Internal size, either alkenyl succinic anhydride (ASA) or alkyl ketene dimer (AKD), is difficult to retain when used alone.
Woodflour was esterified in order to improve its compatibility with the matrix using a commercial alkenyl succinic anhydride (ASA, Lasar 2019 CE, Akzo Nobel).
