Stilbene, oxidative fission

Stilbenes that are used as fluorescent whitening agents are photolytically degraded by reactions involving cis-trans isomerization followed by hydration of the double bond, or oxidative fission of the double bond to yield aldehydes (Kramer et al. 1996). 

The degradation of bisphenol-A involves a rearrangement—analogous to those described for compounds with qnaternary carbon atoms in Chapter 7, Part 1—followed by oxidative fission of the stilbene prodnced (Lobos et al. 1992 Spivack et al. 1994) (Figure 8.38).

The oxidative fission of the C=C bond in a substituted stilbene by Pseudomonas sp. strain TMY1009 to a mixture of aromatic aldehydes involves 1 mol each of substrate and oxygen (Habu et al. 1989).
