Popis: Synthesis of KCC-1 silica sulphuric acid as a new catalyst has been reported. The catalyst was characterized using XRD, SEM, TEM, BET, FT-IR, TGA-DTA, and EDX analysis. The catalytic activity was evaluated for the synthesis of enaminones under solvent-free conditions. The catalyst was easily recovered and reused up to seven cycles with slight loss of activity. The attractive features of this protocol are low amount of catalyst loading, short reaction time, mild reaction conditions, good to excellent yield of the products, easy handling of the catalyst and simple operational procedure. A highly efficient Sulphated nanosilica sulphuric acid has been synthesized and applied for the synthesis of enaminones. This catalytic protocol is better for the synthesis of enaminone than previously reported procedures in terms of catalyst loading, reaction condition, reaction time and yields of the products.
