Examples of Photochemical Transformations in Aqueous Solutions

Illustrative Examples of Photochemical Transformations in Aqueous Solutions 

Methylcyclopentadienyl manganese tricarbonyl that has been suggested as a fuel additive is decomposed primarily by photolysis in aqueous medium. This resulted in the formation of methylcyclopentadiene that may plausibly be presumed to polymerize, and a manganese carbonyl that decomposed to Mn304 (Garrison et al. 1995). 

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). 

Although ethylenediaminetetraacetic acid (EDTA) is biodegradable under specific laboratory conditions (Belly et al. 1975 Lauff et al. 1990 Nortemann 1992 Witschel et al. 1997), 

Photolysis of the oxime group in the pyrazole miticide fenpyroximate resulted in the formation of two principal transformation products the nitrile via an elimination reaction and the aldehyde by hydrolysis (Swanson et al. 1995).
