چکیده
|
Known as a lewis acid which acts as a natural catalyst, bentonite can be used to produce severalarylidene (thio) barbituric acid derivatives through conducting a knoevenagel reaction betweenaromatic aldehydes and (thio) barbituric acid. water is considered as the medium for this reactionand the results are at arange of good to excellent over a reasonable reaction time. this method isnatural and economic as well as convenient to work with, while the reaction time is also short. inaddition to excellent results, this method is also environment-friendly due to the use of water assolvent that broadens the domain of organic synthesis in aqueous medium.
