- 2-BENZENEACETIC ACIDS AFFECTING ROOT GRAVITROPISM
-
A series of new 2-benzeneacetic acids , prepared by basic hydrolysis of 2-substituted 1,3(2H-4H)isoquinolinediones, were studied from the point of view of their antigravitropic activity on germinating seeds of Lens esculenta Moench.The results of the assay showed that the class possesses antigravitropic activity.The most active compounds were the dichlorosubstituted phenyl-derivatives (XXI), (XVII) and (XX), 2-naphthyl- (XXIV), 8-quinolyl- (XXV) and 4-biphenylyl- (IX) derivatives.The activity of the class is generally lower than that of the the homologous N-arylphthalamic acids.Moreover the trifluoromethyl-phenyl- (III) and the 1-naphthyl- (XXIII) derivatives, subjected to herbicidal assay against some common weeds, showed a noticeable activity, with marked selectivity against Dicotyledons.
