Copper(II) complexes of imidazolinone herbicides

Inorganica Chimica Acta, 1997
Abstract The copper(II) complexes formed by the imidazolinone herbicide Imazapyr or (±)-2-4-isopropyl-(4-methyl-5-oxo-2-imidazolin-2-yl)-nicotinic acid (H 2 imz) are described. The compounds isolated in the solid state confirm that Imazapyr is a versatile bipy-like ligand able to chelate the metal ion through two different donor sets.

Efficacy of imidazolinone herbicides applied to imidazolinone-resistant maize and their carryover effect on rotational crops

Crop Protection, 2005
Abstract A field study was performed in imidazolinone-resistant maize in order to evaluate the effectiveness and carryover effect on rotational crops of two formulated mixtures of imidazolinone herbicides: imazapyr plus imazapic and imazapyr plus imazethapyr.

Syntheses of ?-functionally substituted 2-imidazolinones

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1979
1. The Mannich and Vilsmeier reactions with 4(5)-methyl-2-imidazolinone proceed with involvement of the C5(4) carbon atom. 2. The reaction of 4(5)-methyl-5(4)-piperidinomethyl-2-imidazolinone with a mixture of thioacetic acid and acetic anhydride gives 1-acetyl-4-acetylmercaptomethyl-5-methyl-2-imidazolinone. 3.

Abiotic degradation (photodegradation and hydrolysis) of imidazolinone herbicides

Journal of Environmental Science and Health, Part B, 2008
The abiotic degradation of the imidazolinone herbicides imazapyr, imazethapyr and imazaquin was investigated under controlled conditions. Hydrolysis, where it occurred, and photodegradation both followed first-order kinetics for all herbicides.
