ABSTRACT:
Herbicidal 3-substituted pyridine compounds and derivatives thereof of the formula: ##STR1## wherein Ar is a substituted or unsubstituted 5- or 6-membered heteroaryl group having 1, 2 or 3 ring nitrogen atoms with the remainder of the ring atoms being carbon; a substituted or unsubstituted 5-membered heteroaryl group having a ring heteroatom of oxygen or sulfur with the remainder of the ring atoms being carbon; or a substituted or unsubstituted 5-membered heteroaryl group having one ring nitrogen atom and either an oxygen or sulfur ring heteroatom with the remainder of the ring atoms being carbon. Herbicidal compositions containing such 3-substituted pyridine compounds and derivatives thereof and methods of controlling undesirable vegetation employing these compounds and derivatives are also disclosed. The compounds in which XR is hydroxyl are also useful as intermediates for producing the disclosed 3-substituted pyridine derivatives.
