Polyaniline-I(2) is prepared by doping of polyaniline base with iodine. Polyaniline base and polyaniline-I(2) are characterized by infrared spectra, X-ray diffraction spectra, and thermogravimetric analysis. Polyaniline-I(2) is used as a catalyst for the first time in acetalization of carbonyl compounds. The catalyzing acetalization of cyclohexanone and propane-1,2-diol is conducted in excellent yields with simple and more environmental benign procedure. This catalyst could also catalyze acetalization of aromatic and aliphatic carbonyl compounds with satisfactory yields. The use of polyaniline-I(2) catalyst is feasible because of its easy preparation, easy handling, stability, easy recovery, reusability, good activity, and eco-friendly nature.
