Abstract
1H-2-Benzothiopyran-1-ones (isothiocoumarins) and 1H-2-benzopyran-1-ones (i socoumarins) behave dissimilarly on solid state irradiation at room tempera ture as the former photocyclodimerize efficiently while the latter only und ergo slow photodecomposition. Both 4H-naphtho[2,1-c]pyran-4-one and thiopyr an-4-one turn out to be photostable under these same reaction conditions. ( C) 2000 Elsevier Science Ltd. All rights reserved.
