o-Nitroaryldioxolane for protection of pheromones. Study of the photodelivery of carbonylic compounds
o-Nitrophenyldioxolanes 1 to 12 have been prepared and the rate of their photocleavage determined Steric congestion in the molecule causes a decrease of the reaction rate. The decrease in the rate is especially important in the presence of a nitro group in a second phenyl ring.
