• Montmorillonite-KSF encapsulated Cu(OH)x was easily prepared from inexpensive materials.
• The catalyst is stable, easy to handle, leaching free and does not need any additive, ligand or base.
• This heterogeneous catalyst is reusable several times with no significant loss of catalytic activity.
• High conversions with excellent selectivity were obtained at under ordinary conditions.
Cu(OH)x has been encapsulated over montmorillonite-KSF by simple ologomeric deposition strategy. The resulting catalyst has been employed for selective homocoupling of arylboronic acids under ambient conditions without requirement of any ligand or base. This catalyst is easy to recover and shows excellent reusability without losing its activity. Techniques like XRD, SEM, TPR, IR, BET surface area measurement and XPS were used to characterize the catalyst. The present method promises for the simple and clean homocoupling of arylboronic acids.
