Novel Base-Promoted Rearrangement of 2-(4-Cyano-, 2-Nitro-, and 4-Nitrobenzoyloxy)tropones and 2-(2-Oxo-2-phenethyloxy)tropone to 2--tropones and 2-(1-Hydroxy-2-oxo-2-phenethyl)tropone

The base-catalyzed rearrangement of 2-(2-nitro-, 4-nitro-, and 4-cyanobenzyloxy)tropones smoothly yielded corresponding 2-<(aryl)hydroxymethyl>tropones, while their thermolysis gave 3-(arylmethyl)tropolones.This reaction has no precedent analogy in tropon
