Quantitative self-sensitized photooxidation of 1,2-diarylcyclobutene derivatives by singlet oxygen

Kühni, Joël ; Debieux, Jean-Luc ; Belser, Peter

In: Synthesis, 2007, p. 1421-1425

Ligands 1 and 2 underwent quantitative photooxidation when they were reacted with singlet oxygen sensitized by methylene blue. However, the quantitative reaction became self-sensitized for the compound Ru(1) wherein the ruthenium complex acted as a sensitizer.
