Montmorillonite KSF-Catalyzed Synthesis of 2,2′-(Arylmethylene)bis(3-hydroxy-5,5-dimethylcyclohex-2-en-1-ones) for the Functionalization of MCM-41 Silica Nanoparticles

Autor: Lassaad Mechi, Younes Moussaoui, M. Ben Mosbah

Publikováno v: Russian Journal of Organic Chemistry. 57:1533-1539

A green protocol has been developed for the preparation of 2,2′-(arylmethylene)bis(3-hydroxy-5,5-dimethylcyclohex-2-en-1-ones) following the multicomponent condensation reaction between aromatic aldehydes and dimedone with excellent yields. The r
