Abstract

A novel method for the production of singlet oxygen from H<subscript>2</subscript>O<subscript>2</subscript> was developed. A combination of iodoarene (ArI), methyltrioxorhenium (MTO), and H<subscript>2</subscript>O<subscript>2</subscript> in the presence of pyridine as the co-catalyst efficiently produced singlet molecular oxygen (<superscript>1</superscript>O<subscript>2</subscript>) under biphasic conditions. The existence of <superscript>1</superscript>O<subscript>2</subscript> was demonstrated by trapping experiments with aromatic dienes, 1,3-cyclodienes, and alkenes. The mechanism of <superscript>1</superscript>O<subscript>2 </subscript> production from the iodoarene/MTO/35 % H<subscript>2</subscript>O<subscript>2</subscript> system and the reaction scope was also discussed.
