A facile synthesis of novel optically active R,R-2-(4-(2-(4-(5-chloro-3- halo-pyridin-2-yloxy)-phenoxy)-propionyloxy)-phenoxy)-propionic acid esters using cyanuric chloride as potential herbicide

A facile method for the synthesis of a new series of R,R-2-(4-(2-(4-(5- chloro-3-halopyridin-2-yloxy)-phenoxy)-propionyloxy)-phenoxy)-propionic acid ester derivatives containing a halo-substituted pyridine carrying two R,R chiral centers from (R)-2-(4-hyd

Direct formation of 2,3,5-trichloropyridine and its nucleophilic displacement reactions in ionic liquid

Reaction of trichloroacetaldehyde and acrylonitrile in the presence of a catalytic amount of copper (I) chloride in ionic liquid afforded 2,3,5-trichloropyridine, fluprination of which with KF and CsF in ionic liquid afforded 3,5-dichloro-2-fluoropyridihe and 5-chloro-2,3-dichloropyridine. Reaction of 2,3,5-trichloropyridine, 3,5-dichloro-2-fluoropyridine, or 5-chloro-2,3-dichloropyride with 2-(4-hydroxyphenoxy) propionates in ionic liquid afforded the corresponding 2-aryloxylpropionates in good yields.

Sulfamoylphenylureas

The N-acylsulfamoylphenylureas of formula I below are suitable as counter-agents (antidotes or safeners) for protecting cultivated plants from the phytotoxic action of herbicides. Suitable crops are preferably cereals, soybeans, sorghum, maize and rice, and suitable herbicides are sulfonylureas, chloroacetanilides and aryloxyphenoxypropionic acid derivatives. The N-acylsulfamoylphenylureas have the formula I STR1 wherein A is a radical selected from the group STR2 R1 is C1 -C4 -alkoxy or each of R1 and R2, independently of the other, is hydrogen, C1 -C8 alkyl, C3 -C8 cycloalkyl, C3 -C6 alkenyl, C3 -C6 alkynyl, STR3 or C1 -C4 alkyl substituted by C1 -C4 alkoxy or by STR4 or R1 and R2 together form a C4 -C6 alkylene bridge, or a C4 -C6 alkylene bridge interrupted by oxygen, sulfur, SO, SO2, NH or by --N(C1 -C4 alkyl)-, R3 is hydrogen or C1 -C4 alkyl, Ra to Rh, Rx and Ry are as defined in the disclosure.
