Study of copper(II) chloro- and dichloropropionates, crystal and molecular structure of trans-bis(methyl-3-pyridylcarbamate)bis(α,α-dichloropropionato)copper(II)
elemental analysis, IR, electronic and EPR spectra. All the CuX2L2 compounds seem to possess octahedral copper(II) stereochemistry with differing tetragonal distortion. Complex [Cu(CH3CCl2COO)2(mpc)2] was also studied by X-ray analysis. The structure of [Cu(CH3CCl2COO)2(mpc)2] is centrosymmetric. The Cu(II) atom is pseudo-octahedrally trans-coordinated by four carboxylic oxygen atoms of α,α-dichloropropionate

Dextrorotatory 2-phenoxypropionic acids are made by heating an alkali metal salt of dextrorotatory 2-chloropropionic acid with an alkali metal phenate in an inert organic solvent of high boiling point under reflux.
