Through the use of two capillary GC columns: 40% octadecyl/ 15% phenyl methyl siloxane and 50% phenyl methyl siloxane, it was possible to separate 201 PCB congeners with only four unresolved pairs. The data compiled in this study for all 209 congeners will aid in the identification of selected individual components of these environmental pollutants. The use of this data also presents the opportunity for the improved quantification of the commercial PCB formulations. -from Authors
Aryl(pentachlorophenyl)nickel(II) complexes. Lack of free rotation about tolyl-nickel bonds and lack of ortho effect in carbonylation

A series of complexes of the type trans-R(C6Cl5)Ni(PPhMe2)2 (where R = aryl) was prepared. Their 1H NMR spectra indicate that both R = o-tolyl and m-tolyl groups are oriented perpendicularly to the nickel coordination plane. Reaction of carbon monoxide with these complexes gave, under mild conditions, R(C6Cl5)CO for R = aryl groups including o-tolyl but not for 2-furyl and its analogues. The o-tolyl complex was exceptionally stable toward thermal reductive elimination in tetrachloroethylene under air. Factors affecting the relative reactivities of these complexes are discussed, based mainly on the early explanation for the so-called ortho effect .
