β¦ Synopsis
In contrast to carbonyl compounds, the 17O chemical shifts of aryl sulfoxides are deshielded by electron donor substituents and show only slight sensitivity. In a thiirene-1-oxide the e β ect of interaction between the CxC and SΓO groups is also small.

## Abstract It it shown that the photoβoxidation of aromatic molecules containing an active methylene group can be used to introduce isotopic oxygen. Photoβoxidation of xanthene results in the formation of xanthone with the oxygen label appearing in the product at the carbonyl group. In this way, 1
