A study on the addition of some carboxylic acids to epichlorohydrin in the presence of salen chromium(III) complexes
The effect of salen ligands on the catalytic activity and regioselectivity of chromium(III) ions in the addition reaction of aliphatic carboxylic acids to epichlorohydrin was studied. It was found that coordination of chromium(III) ions by tetradentate Shiff's bases decreased their catalytic activity in comparison to chromium(III) acetate. Slightly worse regioselectivity was also detected. Moreover, an increase of the regioselectivity of the addition with decreasing temperature was observed. (C) 2003 Elsevier Science B.V.
