Abstract
Novel compounds, N-acetyl-polychlorobenzamides, are prepared by treating corresponding polychlorobenzonitrile compounds with acetic acid in a closed reactor at an elevated temperature above the boiling point of the acetic acid. These new compounds have been found to be useful biological chemicals, particularly in controlling undesirable vegetation, and also useful as chemical intermediates.
