Abstract
|
|
|
|
Photoreactions of pseudosaccharin pyridinemethyl ethers have been investigated. Pseudosaccharin 2-pyridinemethyl ether, pseudosaccharin 4-pyridinemethyl ether and pseudosaccharin 3-pyridinemethyl ether all undergo a facile photoreaction via reaction pathways involving homolysis of the bond between pseudosaccharyl oxygen and pyridinemethyl carbon, and excited nucleophilic substitution of pyridinemethoxy group by solvent, methanol which are not quenched by oxygen present in the reaction. Product yield demonstrates that the homolysis pathway predominates over the nucleophilic substitution.
