One goals project was use phenolic acid phytochemicals catalytic process. newly synthesized nanocomposites were characterized by several analytical...

An ionic liquid containing copper(I) is introduced as a new, green, homogeneous, and reusable catalyst for click synthesis of 1,4-disubstituted-1H-1,2,3-triazoles from α-azido ketones terminal alkynes in various solvents, especially [bmim]BF4. These cyclization reactions were efficiently performed the presence with short reaction times good yields. This catalytic exhibits excellent activity can be simply recovered reused at least five runs without any loss its activity.

Macroporous polymer supported nanoparticles of copper(I) iodide catalyst and macroporous azide reagent were used to simplify the synthesis 1,4-disubstituted-1H-1,2,3-triazoles from various benzyl halides following green chemistry principles. This new one-pot protocol facilitates workup reaction provides products in short times at high yields. Heterogeneous can be reloaded reused least for 5 runs without significant decrease

Abstract L‐prolinate anion immobilized onto amberlite IRA900OH ([Amb]L‐Prolinate) is reported as a new, reusable and cheap organocatalyst for the condensation of indoles with isatins to afford corresponding 3,3′‐diaryloxindol derivatives in ethanol under reflux condition. [Amb]L‐Prolinate was achieved by treatment MeOH/H 2 O solution L‐proline at 60 °C. The procedure heterogenization based on non‐covalent ion‐pair immobilization surface anion‐exchange resin (AmbIRA900OH) commercially...

In a straightforward and fast protocol, mixture of 1,3-dimethylimidazolium fluoride ([DMIM]F) 1-butylimidazolium tetrafluoroborate ([Hbim]BF₄) efficiently catalyzed the reaction epoxides with ketene silyl acetals (KSA) to give various γ-lactones under metal-free conditions. Diverse kinds desired were directly prepared high regioselectivities yields in simple one-pot procedure using [DMIM]F as Si-O bond activator [Hbim]BF₄ solvent acidic ionic liquid catalyst. The was recovered reused three...

The first catalytic approach to the nucleophilic addition of silyl ketene acetals 2 epoxides 1 is reported. defined protocol metal-free using tetrabutylammonioum fluoride as catalyst. It works in a very efficient manner under solvent-free conditions (SolFC) allowing γ-lactones 3 be directly obtained with high regioselectivities and yields.
