AM1 and Single-crystal X-ray Diffraction Study of the Conformational Properties of Chlorinated Diphenyl Ethers

Structural and conformational properties of 11 polychlorinated diphenyl ethers (PCDEs) 1-11 and thyroxine derivative 12 were studied by the semiempirical AM1 method.In addition, the molecular structures of six PCDEs 1-6 were solved by X-ray crystallograph

Synthesis, Structure Verification, and Chromatographic Relative Retention Times for Polychlorinated Diphenyl Ethers

Fifty-four polychlorinated diphenyl ether (PCDEs) congeners were synthesized, and their structures were confirmed by mass spectrometry and proton magnetic resonance spectroscopy. The gas chromatographic relative retention times (RRT) for the PCDEs were determined relative to a reference standard, -tetrachlorobiphenyl (PCB 77) on the fused silica capillary columns of SE-54 and OV-1701. The retention times for PCDEs increased with the increasing number of vicinal chlorines within a series of isomers. The chlorine substitution patterns of PCDEs were used to develop a method for predicting RRTs for congeners that were not synthesized.
