methoxybenzophenone3 upon irradiation, but the yields are low both in hexane and in methanol.p-Methoxyphenylo-acetoxybenzoate1 undergoes photo-Friesrearrangement, affording 2′ - acetoxy - 2 - hydroxy - 5 - methoxybenzophenone4 in good yield. Compound4 is not stable in silicagel: it isomerizes to 2′ - acetoxy - 2 - hydroxy - 5′ - methoxybenzophenone5, that is also the major acetylation product of3 with acetyl
