We reported the functionalization of multiwalled carbon nanotube (MWCNT) with 4-aminobenzoic acid by a ‘‘direct’’ Friedel–Crafts acylation reaction in a mild polyphosphoric acid (PPA)/phosphorous pentoxide (P2O5) medium. The resulting 4aminobenzoyl-functionalized MWCNT (AF-MWCNT) was used as a platform for the grafting of polypyrrole (PPy) in ammonium persulfate (APS)/aqueous hydrochloric acid ...
Isatin, also known as 1H-Indole-2, 3-Dione, is an eight-carbon containing endogenous compound found in nature. Erdmann and Laurent synthesized isatin 1840, before it was discovered It versatile distributed tissues body fluids. Isatins have been detected mammalian tissue, their function a biochemical process modulator has the focus of many debates. The moiety shows some important chemical reacti...
To endorse sufficient water affinity to multiwalled carbon nanotubes (MWCNTs), dendritic hyperbranched poly(ether-ketone) (HPEK) was first covalently grafted to the surface of a MWCNT via a Friedel-Crafts acylation reaction. The resultant HPEK-grafted MWCNT (HPEK-g-MWCNT) was subsequently sulfonated in chlorosulfonic acid to produce sulfonated HPEK-g-MWCNT (SHPEK-g-MWCNT), which is dispersible ...
An important advance in fluid surface control was the amphiphilic surfactant composed of coupled molecular structures (i.e., hydrophilic and hydrophobic) to reduce surface tension between two distinct fluid phases. However, implementation of simple surfactants has been hindered by the broad range of applications in water containing alkaline earth metals (i.e., hard water), which disrupt surfact...
The present study describes the synthesis and pharmacological evaluation of 2-substituted-6-(4-acylaminophenyl)-4,5-dihydropyridazin-3(2H)-ones as potent inodilating agents. The synthesis of target compounds 2-4 and 7-11 was achieved by Friedel-Crafts acylation of appropriate anilide derivative with succinic anhydride or methylsuccinic anhydride and subsequent cyclization of intermediary keto a...
