Elimination pyrolytic, coupled

The isotopic studies of the mechanism of this reductive elimination process, involving breaking of M—C bonds followed by formation of C—C bonds, have been initiated by synthesis of (dimethyl-d6)(2,4-pentanedionato)gold, 73-(CD3)2, and identification of coupled reaction products produced in the pyrolytic decomposition carried out in sealed quartz NMR tubes in CD3OD and CV,Di2 solvents. 

They established gas chromatographic and mass spectrographic procedures coupled with sensory threshold odor analysis for the determination of off-flavor emanation from packaging materials. They found reaction products from the polymeric materials as well as a combination of oxidation and pyrolytic elimination reactions in polyethylene or paperboard to be responsible for off-odors.
