Biomass alkali-rich ash as catalyst for one-pot synthesis pyridine derivatives under solvent-free condition
Biomass alkali-rich ash as catalyst for one-pot synthesis pyridine derivatives under solvent-free condition...
Regioselective Synthesis of E-Oximes Catalyzed by Ferric Chloride under Solvent Free Conditions
In conclusion, the reported procedure is a novel method for the facile preparation of
ketoximes in solvent-free media. In addition, this simple and readily available reagent affords
various ketoximes in good to excellent yields (85...
Preparation of 1,5-Fused Tetrazoles under Solvent-Free Conditions
A facile and efficient procedure is developed for a one-pot synthesis of fused
1,5-disubstituted tetrazoles from cyclic ketones and sodium azide in the presence of
aluminum chloride in solvent-free media. Advantages of this method...
Comparison between the activity of nano-catalysts of Al-promoted and pure sulfated ziconia and optimization of condition in esterification of oleic acid
Preparation of suitable catalysts has been concerned in production of biodiesel from oil with high FFA as west cooking oil. In this study, the catalytic activity of prepared Al-promoted and pure sulfated zirconia by solvent-free method...
Ionic liquids as highly efficient and reusable catalyst for one-pot synthesis of bis-α-aminophosphonate
Ionic liquids (ILs) have gained great attention in recent years [1]. ILs have a high polarity and low vapor pressure. These characteristics combined with immiscibility with most of the less polar organic solvents led to ...
Ferric hydrogensulfate catalyzed aerobic oxidative coupling of 2-naphthols in water or under solvent free conditions
The symmetric oxidative coupling reactions of 2-naphthol derivatives with both ferric hydrogensulfate in water and silica ferric
hydrogensulfate in solvent free conditions were carried out. The advantages of this green procedure are...
Preparation of Nano-Size Al-Promoted Sulfated Zirconia and the Impact of Calcination Temperature on Its Catalytic Activity
Solvent-free technique was employed in this work in order to assess the influence of the calcination temperature on the activity of Al-promoted sulfated zirconia. The catalyst was analyzed by XRD and IR-spectrum method, and catalytic activity...
Preparation of alumina supported super active sulfated zirconia and assessment of its activity in esterification reaction
In this work, the optimal percentage of alumina loading on sulfated zirconia by solvent-free method was investigated and its reusability was assessed. To obtain these objectives, sulfated zirconia was supported with different molar percentage...
Efficient synthesis of naphthalene-fused dilactam crown ethers
The novel macrocyclic dilactams that structurally fuse to naphthalene chromophore were synthesised. These
compounds were obtained in the macrocyclisation step by fast addition methods and the results were compared
with solvent-free...
