Consequences of hydrophobic association in photoreactions: photodimerization of alkyl cinnamates in water
Photolysis of alkyl cinnamates in water gave δ-truxinates in near quantitative yields. Dimerization of alkyl cinnamates at low concentration (about 10−4 M) in water is attributed to hydrophobic association of these solutes. At such low concentrations, photolysis in benzene and methanol yields only geometric isomers. This study illustrates the potential of water as a solvent for photoreactions and stresses the need for increased appreciation of its utility.
