The present invention relates to esters of carboxylic acid agrochemicals comprising a labile protecting group and having formula (I). Certain of the esters of carboxylic acid agrochemicals do not undergo hydrolysis to a significant degree in the dark, but are cleaved to regenerate the parent carboxylic acid agrochemical when exposed to light. Others of the esters of carboxylic acid agrochemicals undergo hydrolysis under both light and dark conditions. The present invention further relates to methods for the controlled release of a carboxylic acid agrochemicals, and to methods of controlling unwanted plants comprising applying to the unwanted plants an ester of a carboxylic acid agrochemical.

bicyclic analogs, as well as imides of carboxylic and sulfonic acids and substituted hydrazines with mixtures of sulfuric and nitric acids. The kinetic study of the reaction mechanism was performed using UV and NMR spectroscopy. It was found that the NO2 groups were sequentially introduced into the methylene fragment by the addition of the nitronium ion to multiple bonds of intermediate enols followed
