Uses

Different sources of media describe the Uses of 50-31-7 differently. You can refer to the following data:
1. An all-purpose, non-selective, pre-emergent and early post-emergent herbicide.
2. Systemic growth-regulator herbicide used for postemergence control of broad-leaved perennial and annual weeds in cereals and grass seed crops.

Definition

A substituted benzoic acid that is a potent synthetic auxin.

Safety Profile

Poison by intraperitoneal route.Moderately toxic by ingestion and subcutaneous routes.When heated to decomposition it emits toxic fumes ofClí. Used as an herbicide.

Environmental Fate

Photolytic. Plimmer (1970) postulated that the irradiation of 2,3,6-trichlorobenzoic acid in methanol will undergo dechlorination forming 2,3-, 2,6- and 3,6-dichlorobenzoic acids. Further irradiation may yield 2- and 3-chlorobenzoic acids which may ultimately form benzoic acid (Plimmer, 1970).Chemical/Physical. Reacts with alkalies and amines forming water-soluble salts.

A preparing method of 2-methoxy-3,6-dichlorobenzoic acid

A preparing method of 2-methoxy-3,6-dichlorobenzoic acid is disclosed. The preparing method includes etherifying 2,3,6-trichlorobenzoic acid in methanol under action of sodium methoxide to prepare the 2-methoxy-3,6-dichlorobenzoic acid, wherein the mole ratio of the 2,3,6-trichlorobenzoic acid to the sodium methoxide is 1:1-1:10. The preparing method also includes a step of subjecting a compound shown as a formula 2 to chlorination, tertiary butyl or sulfo group removing and oxidation to prepare the 2,3,6-trichlorobenzoic acid. The preparing method is simple in operation, low in raw material cost, low in production cost, convenient in after-treatment, mild in reaction conditions, environmental friendly, high in yield, short in reaction time and suitable for industrial production.

Carboxylation of C-H bonds using N -heterocyclic carbene gold(I) complexes

A highly efficient [(NHC)AuI]-based (NHC = N-heterocyclic carbene) catalytic system for the carboxylation of aromatic and heteroaromatic C-H bonds was developed. The significant base strength of the Au-OH species is at the origin of the activation process and permits the facile functionalization of C-H bonds without the use of other organometallic reagents.
