A balance on the hydrophobicity and hydrophilicity of SBA-15-SO3H with fluoroalkyl-chained alcohols (RFOH/SBA-15-Pr-SO3H) and its effect on the catalytic activity

A superior catalytic activity for SBA-15 functionalized sulfonic acid content fluoroalkyl chains alcohols as RFOH /SBA-15-Pr-SO3H adduct was found. The fluoroalkyl chains alcohols caused a remarkable increase in catalyst activity. RFOH/SBA-15-Pr-SO3H adduct was found to be an efficient, ultra-fast and waste-free approach for the synthesis of the highly substituted imidazoles. The advantages of the this method include low catalyst loading, simple procedure, waste-free and direct synthetic entry to excellent yield of products, high reusability, and short reaction time.
