Herbicidal substituted hydroxybenzyl-heteroaryl compounds and derivatives thereof of the formula [Figure] wherein Ar is a substituted or unsubstituted 5- or 6-membered heteroaryl group having 2 or 3 ring nitrogen atoms or a substituted or unsubstituted 5-membered heteroaryl group having two ring het
Herbicidal substituted hydroxybenzyl-heteroaryl compounds and derivatives thereof of the formula [Figure] wherein Ar is a substituted or unsubstituted 5- or 6-membered heteroaryl group having 2 or 3 ring nitrogen atoms or a substituted or unsubstituted 5-membered heteroaryl group having two ring heteroatoms, one of the ring heteroatoms being nitrogen and the other being sulfur or oxygen. Herbicidal compositions containing such substituted hydroxybenzyl-heteroaryl 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 substituted hydroxybenzyl-heteroaryl derivatives.
