This study is the first report of the application of sulfonated multi-walled carbon nanotubes (MWCNTs-SO3H) in the synthesis of tetrahydrobenzo[a]xanthene and tetrahydrobenzo[a]acridine derivatives. The catalyst was prepared via a chemical approach and the sulfonated groups were attached to the side-wall of MWCNTs with total density of 2.58 mmol.g-1. In order to prove functionalization of the […]
In this research, we develop and prepare some of the polymers based on polythioesters using cetrimide as an ionic liquid and phase transfer catalyst. All of the polymers were prepared through the reaction of 5,5′-methylenebis (1,3,4-oxadiazole-2-thiol) with five types of diacyl chloride derivatives in the presence of cetrimide as phase transfer catalyst in the mixture […]
Pyrimido[4,5-b]quinolones play a significant role in medicinal chemistry owing to their various biological properties, including antihistaminic, antimalarial, antifungal, anticancer, antioxidant, antiviral, anti-microbial, and anti-inflammatory activities. A dual acidic ionic liquid anchored on graphene oxide nanosheets (GO-Si-Pr-Lysin-SO3H) was provided and characterized using transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA), […]
