Journal ArticleDOI
Ferrospinels based on Co and Ni prepared via a low temperature route as efficient catalysts for the selective synthesis of o-cresol and 2,6-xylenol from phenol and methanol
TL;DR: In this article, the alkylation of phenol with methanol is conducted over Ni 1− x Co x Fe 2 O 4 (x = 0, 0.2, 0., 0.5, 1.8, and 1.0) type systems prepared via low temperature route.
Journal ArticleDOI
Clay supported titanium catalyst for the solvent free synthesis of tetrasubstituted imidazoles and benzimidazoles
TL;DR: A series of clay supported metal containing catalysts were prepared and their catalytic performance was evaluated in the synthesis of tetrasubstitued imidazoles under solvent free condition as discussed by the authors.
Journal ArticleDOI
A comparison on the catalytic activity of Zn1−xCoxFe2O4 (x = 0, 0.2, 0.5, 0.8 and 1.0)-type ferrospinels prepared via. a low temperature route for the alkylation of aniline and phenol using methanol as the alkylating agent
TL;DR: In this article, aniline and phenol methylation using methanol as the alkylating agent was investigated and an attempt was made to interpret the observed trends based on the variation of surface acid-base properties of the catalyst surface with changes in the spinel composition.
Journal ArticleDOI
A New Green and Efficient Brønsted: Lewis Acidic DES for Pyrrole Synthesis
TL;DR: Deep eutectic solvents (DESs) are fluids composed of different Lewis or Bronsted acids and bases, generally acknowledged as new analogues to ionic liquids (ILs), because of their similar characteristics, but with more advantages related to preparation cost, environmental impact etc as mentioned in this paper.
Journal ArticleDOI
A comparative study on aniline alkylation activity using methanol and dimethyl carbonate as the alkylating agents over Zn-Co-Fe ternary spinel systems
TL;DR: In this paper, the authors compared the performance of methanol and DMC as an alkylating agent for N-monomethylation of aniline using Zn-Co ferrites.
