Production, characterization, and application of a novel chitosan-g-maleic anhydride and modified graphene oxide nanocomposite, supported methane sulfonic acid, for efficient synthesis of 1-(benzothiazolylamino) methyl-2-naphtols
this paper to fabricate 1-(benzothiazolylamino) methyl-2-naphthols using a novel green nanocomposite of chitosan and diethylenetriamine-modified grapheneoxide, supported methanesulfonic acid (Ch@GO-DETA.MSA.). For the synthesis of the nanocomposite, maleic anhydride was first attached to chitosan, and then, grapheneoxide was modified by diethylenetriamine (GO@DETA). Subsequently, nanocomposite was

In this study, post modification of the imidazole units in the porous organic polymer (POP) the formation of imidazolium salt is reported. Addition of FeCl to anionic moiety of POP leads to synthesis of magnetic ionic POP namely Im-MIPOP which is applied as a heterogeneous catalytic system. This polymer was characterized by different analytical techniques including Fourier transform infrared (FT-IR)

2-(diarylalkyl)aminobenzothiazoles were designed based on commercial synthetic calcium channel blockers (CCBs) and angiotensinconvertingenzyme (ACE) inhibitors. Which are further modified based on the natural products which are angiotensinconvertingenzyme (ACE) inhibitors. Completely green protocol was developed for their synthesis. As they are initially designed based on CCBs, they were screened for
