## Abstract The positions of acetyl groups introduced by Friedel‐Crafts reactions into 2,3‐diphenylbenzofuran and its derivatives monomethylated in the 5,6 and 7 positions and dimethylated in the 5,6 positions were determined by means of single and double resonance NMR spectra. It was found that th
