Novel and Efficient One Pot Condensation Reactions between Ketones and Aromatic Alcohols in the Presence of CrO 3 Producing α , β ‐Unsaturated Carbonyl Compounds

We report a new, effective and simple method for preparing α , β ‐unsaturated carbonyl compounds by reacting ketones and aromatic alcohols at 56°C in the presence of CrO 3 (CrO 3 acts as an oxidant and also a catalyst) for around 10 h. The condensation reactions occurred effectively among a wide combination of ketones and alcohols. The procedure is simple and the yields can be high up to 98%. And a probable mechanism is proposed.
