摘要：
Methylene blue sensitized photooxygenation of 3- arylidene-2-aryl-2,3-dihydro-4H-l-benzopyran-4-ones (1 a-d) has provided 3-C-aroyl-2-aryl-4H-l-benzopyran-4-ones (2a-d) in moderate to good yield. A plausible mechanism for the reaction involved has been suggested. Copyright © 1990 by Taylor & Francis Group. All rights reserved.
