Abstract

The photocatalyzed oxidation of indole (1) in an aqueous suspension of titanium dioxide has been investigated and an attempt has been made to identify the products formed during the photooxidation process by gas chromatographic-mass spectrometric (GC-MS) analysis. Photolysis of an aqueous solution of indole (1) in the presence of titanium dioxide and oxygen led to the formation of 2,3-dihydroindole- 2-one (6) and 1H-indole-2,3-dione (7). A probable pathway for the formation of these products has been proposed.
