    • The photoreactions became cleaner and more PPG reagent V could be obtained with more water as the cosolvent, albeit the yields of released carbonyl compounds were not affected. Taking into consideration of the poor solubility of the studied acetals in highly polar solvent systems, we conducted most of the photoreactions in acetonitrile/water (9:1). Photo deprotection reactions carried out in methanol did not provide cleaner reactions and better yields of released aldehydes than in acetonitrile/water (9:1). Instead some dimethyl acetal byproducts were detected in methanol. Reactions in other solvent systems were previously discussed. (5a, 5c)
