The enantiomer separation of 2-halocarboxylic acid esters on two chiral nickel(l1) bis-((perfluoroacy1)terpeneketonates) by complexation gas chromatography is described. The quantitative enantiomer separation of branched 2-halocarboxylic acid esters is achieved with nickel ( 11) bis (3-(heptafluorob
