摘要

There are provided novel 5(and/or 6)substituted 2-(2-imidazolin-2-yl) and 2-(2-imidazolidinyl)nicotinic acids, esters and salts, which are useful as herbicidal agents. There are also provided novel substituted pyrrolopyridine acetonitriles, pyrrolopyridine acetamides, imidazopyrrolopyridinediones and carbamoylnicotinic acid esters, that are useful as intermediates for the preparation of the above said herbicidal agents.
