A simple and eco-friendly Montmorillonite K10 (MK10) catalyzed method for the synthesis of cyclopentenone derivatives from biomass-produced furfural has been developed. The versatility of this protocol is that the reactions were carried out in solvent free condition and in short reaction time under heterogeneous catalysis. Montmorillonite K10 is a material most explored as heterogeneous catalyst since it is inexpensive and environmentally friendly.

A series of N,N′-alkylidene bisamides were prepared via a green and environmentally friendly synthetic protocol from the reaction of phenyl acetylene or hex-1-yne, aromatic aldehyde, and benzamide or acetamide. Silica-supported barium chloride (SiO2–BaCl2) catalyzes the process of the reaction. The prepared catalysts were characterized by X-ray diffraction, and the products were obtained with high conversions and yields.
