Direct Method of Preparing Propanil Rice Herbicide from 3,4-Dichloronitrobenzene in Kilogram Scale

Author

Abstract

Propanil is one of the most effective rice herbicide which has been produced in good yield and easy
method from 1,2-dichlorobenzene with nitration to 3,4-dichloronitrobenzene and then reductive
amidation with iron powder in propanoic acid. Ease of operation, less reaction steps than previous
approaches, lack of rugged process such as hydrogenation and using of inexpensive reactants are some
performance of presented method.
