Iron-Doped Single-Walled Carbon Nanotubes as New Heterogeneous and Highly Efficient Catalyst for Acylation of Alcohols, Phenols, Carboxylic Acids and Amines under Solvent-Free Conditions
single-walled carbon nanotubes (Fe/SWCNTs) represent an efficient and new heterogeneous reusable catalyst for the acylation of a variety of alcohols, phenols, carboxylic acids and amines with acid chlorides or acid anhydrides undersolvent-freeconditions. The reactions of various primary, secondary, tertiary, and benzylic alcohols, diols, phenols, as well as aromatic and aliphatic amines give acylated
