23. - which comes from CAN was confirmed by ESI-MS.
24. Self-decomposition of the phenoxyl radical species gave a complicated mixture of products. An ESI mass spectrum of the resulting mixture indicated the formation of some S-oxygenated and N-dealkylated products of the ligand.
25. Benzaldehyde was the only product detected by GC-MS, and no C-C coupling products such as hydrobenzoin [PhCH(OH)CH(OH)Ph] were observed.
