SOLVENT FREE AND MICROWAVE ASSISTED SYNTHESIS OF 4- SUBSTITUTEDCALIX8ARENES AND 4-SUBSTITUTEDCALIX4ARENE DERIVATIVES IN PRESENCE K2CO3

摘要

The present invention describes a novel process for preparing p-methylcalix[4]arene (IX); p-phenylcalix[4]arene (X); p- benzylcalix[4]arene (XI); p-cumylcalix [4] arene (XII); p-methoxy calix[4]arene (XIII); p-carbomethoxycalix[4]arene (XIV ) ; p- tertbutylcalix [8]arene (XV) in presence of K2CO3 under solvent free and microwave irradiation.
