چکیده
friedel–crafts synthesis of triarylmethanes over 3-methyl-1-sulfonicacid imidazolium tetrachloroaluminate under green conditions:in this work, friedel–crafts (fc) alkylation of various arenes with aromatic aldehydes catalyzed by 3-methyl-1-sulfonic acid imidazoliumtetrachloroaluminate {[msim]alcl4}, as a green catalyst, to prepare triarylmethanes (tams) has been carried out. some aromatic aldehydes were reacted with arenes containing electron-donor substitutions such as anisole, veratrole, phenols, indole and 2-naphtole under solvent-free conditions. the catalyst was recovered and reused successfully for four times. simple methodology, easy work up, solvent-free condition and excellent yields are some advantages of this work.the promising points for the presented method are high yield, green reaction profile, easier work up and simplicity which make it a useful process for the preparation of various triarylmethanes

متن کاملNanoalumina sulfonic acid catalyzed rapid N-formylation under solvent-free conditions
A rapid and chemoselective method for the N-formylation of structurally diverse anilines with formic acid using nanoalumina sulfonic acid (NASA) at 70oC under solvent-free condition has been developed. The catalyst was found to be compatible with different functional groups and the formylation proceeded smoothly with anilines bearing electron withdrawing as well as electron donating substituents.
متن کاملSynthesis of Some Biginelli-type Products: Nano Alumina Sulfonic acid (NASA) Catalyzed under Solvent-free Condition
Biginelli-type reaction was developed by means of a three-component condensation of analdehyde, ethyl acetoacetate, urea or thiourea and nano alumina sulfonic acid (Al2O3-SO3H)(NASA) as catalyzed. It is carried out under different conditions. In all conditions, the desiredproducts are obtained in high yields after relatively short reaction times. Nevertheless, thereactions proceeded faster and ...
