Photochemical behaviour of 5-bromo-2-furyl ketones : Synthesis of 5-aryl-2-furyl ketones

The photochemical behaviour of the compound 8 was studied. The irradiation of a 10 -3 M solution of 8 in aromatic solvents gave high yields of 9 The irradiation of 8 in ethereal or amine solution quantitatively gave 10 The comparison of reaction rates and quantum yields in different solvents gave re...

Zusammenfassung:	The photochemical behaviour of the compound 8 was studied. The irradiation of a 10 -3 M solution of 8 in aromatic solvents gave high yields of 9 The irradiation of 8 in ethereal or amine solution quantitatively gave 10 The comparison of reaction rates and quantum yields in different solvents gave results in agreement with the hypothesis of an exciplex formation.
