In this work, we describe the synthesis of the amino compounds ( 5a ) and ( 5b ), and the benzimidazoles ( 6a ), ( 6b ) and ( 6c ). These amino compounds and the benzimidazoles were obtained by catalytic hydrogenation of two widely used pesticides – flumetralin ( 4a ) and trifluralin ( 4b ). The reactions described are simple to perform, and generate no chemical wastes. The structures of the compounds were determined through MS and NMR data.
Key words: Trifluralin, flumetralin, benzimidazoles, catalytic hydrogenation.
