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.
本发明涉及包含易变保护基团并具有式(I)的羧酸农用化学品酯。某些羧酸类农用化学品酯在黑暗中不会发生显著程度的水解,但在光照下会发生裂解,再生出母体羧酸类农用化学品。其他羧酸酯类农用化学品在光照和黑暗条件下都会发生水解。本发明还涉及控制释放羧酸类农用化学品的方法,以及控制有害植物的方法,包括向有害植物施用羧酸类农用化学品的酯。
