## Abstract The enol acetate **1b** undergoes benzoylโoxygen bond rupture upon irradiation, giving a mixture of benzophenones **4** and **5**. The primary photoโFries products **2** and **3** could not be isolated, due to a rapid intramolecular transacetylation. The acetophenone **6** rearranges to

Abstract
Enolโesters 1aโ1e undergo clean PhotoโFriesโrearrangements without side reactions. With anthroyl derivatives the reaction is observed only at 254 nm, not at 366 nm.

## Abstract Alkyl substituents on C~ฮฒ~ of the C๏ฃฟC double bond hinder both photodimerization of endocyclic oxaโenones (**1**โ**4**) and their photocycloaddition to olefins, and they cause a loss of regiospecificity in dimerization in unpolar solvents. The oxaโenone **3** which like the bicyclic comp
## Abstract The aim of this study was to evaluate the effects of irradiance, light emission wavelength, and heating of different light curing units on the Knoop and Vickers hardness of a hybrid composite resin. The specimens were irradiated during 40 s with ten different light curing units, LEDs, a
