Abstract

Binding of 3,5‐ditertiarybutyl catechol to Ru(III)(Salen) in aqueous solution of SDS micelle produce [Ru(III)(Salen)(DTBC)]‐ adduct. The redox
potential of the DTBSQ/DTBC couple was found at ‐0.234V versus Ag‐AgCl reference in aqueous micelles. EPR spectra in aqueous solution and
under anaerobic condition show the presence of a semiquinone radical (DTBSQ). The Ru(II)‐DTBSQ complex is susceptible to attack by molecular
oxygen leading to an extradiol cleavage product which, after further reaction, give 4,6‐ditertiarybutyl‐2‐pyrone as the final product.
