✦ Synopsis
Comparison of the herbicidal activities of compound 1, with no branching, and compound 2 indicates that introduction of a methyl group results in a considerable increase in herbicidal activity (Table ); however, compound 2 does not show selectivity towards rice. Compound 4, with a mono¯uoromethyl group, has similar activity to compound 2 but shows less damage to rice. Replacement of a mono¯uromethyl with a di¯uoromethyl or a monochloromethyl group (compounds 5 and 6, respectively) results in decreased herbicidal activity.
