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.
