3'-(Substituted

3'-(Substituted phenyl)-spiro[isobenzofuran-1(3H),5'(4'H)-isoxazol]-3-ones have been found to be effective as herbicides and plant growth regulants, especially for the regulation of soybeans.

3-Aryl-isoxazol-5-yl benzoic acid and salts thereof are prepared by base treatment of 3'-(Aryl)-spiro[isobenzofuran-1(3H),5'(4'H)-isoxazol]-3-one.

Preparation of 3-aryl-isoxazol-5-yl-benzoic acid and salts thereof

2-(3-Aryl-5-isoxazol) benzoyl halide is prepared by treating 3'-(Aryl)-spiro[isobenzofuran-1(3H), 5'(4'H)-isoxazol]-3-one with a reactive halide and water.

Preparation of 2-(3-aryl-5-isoxazol) benzoyl halide

3-Aryl-isoxazol-5-yl benzoates are prepared by an acid catalyzed solvolysis of 3'-(Aryl)-spiro[isobenzofuran-1(3H),5'(4'H)-isoxazol]-3-one.

Preparation of 3-aryl-isoxazol-5-yl benzoates

2-(3-Aryl-5-isoxazolyl)benzoic acids are prepared by thermolysis of 3'-(Aryl)-spiro[isobenzofuran-1(3H),5'(4'H)-isoxazol]-3-one.
