Abstract
A few fluorinated 3-hydrazino-1,2,4-triazino[5,6-b] indoles ( 5 - 8 ) have been synthesized and screened for their herbicidal effect. Treatment of 3-hydrazino-8H/8-fluoro-1,2,4-triazino[5,6-b] indoles ( 3 and 4 ) with fluorinated acyl derivatives ( A and B ) yielded the rich fluorine 1,2,4-triazino indole. Structure of the products have been established by elemental analysis and spectral measurements. The presence and position of fluorine atoms have been deduced from 19 F NMR. The novel fluorinated hydrazino-1,2,4-triazino[5,6-b] indoles have been tested for post-emergent herbicidal activity against grass weed species and broadleaf weed species.
