- Abstract
A series of novel α,α,α-trifluoro-m-tolyl pyridazinone derivatives was synthesised. Herbicidal activities of the two intermediate compounds and 15 pyridazinone derivatives were evaluated through barnyardgrass and rape cup tests and Spirodela polyrrhiza (L.) Schleiden tests. Selected compounds were also evaluated under greenhouse conditions. Bleaching activities were observed at 10 µg ml-1 and some compounds exhibited herbicidal activities at a rate of 300 g ha-1. The relationship between crystal structures and herbicidal activities is discussed through a comparison of two compounds (5a and 5f).
