Elimination reactions of (E)-O-pivaloylbenzaldoximes promoted by Et3N-MeCN, t-BuOK-t-BuOH and t-BuOK-DMSO have been studied kinetically.The reactions produce benzonitrile quantitatively.The reactions are second-order and exhibit substantial values of ρ, β, and kH/kD and an E2 mechanism is evident.The rate of elimination from (E)-O-pivaloylbenzaldoxime increased with base-solvent system variation and gave relative rates of 1, 14.8, and 4.31*104 for Et3N-MeCN, t-BuOK-t-BuOH, t-BuOK-DMSO, respectively.The kH/kD value increased, but the Hammett ρ value increased and then decreased, with this change in the base-solvent system.These results are compared with the predictions of the More O'Ferral-Jencks reaction coordinate diagramm to assess its scope and limitations in the interpretation of the elimination reactions.

experimental part, p. 148 - 151 (2009/12/06)
Preparative syntheses from anisaldehyde 1 of the anti-isomer of anisaldehyde oxime 2 and anisaldehyde oxime esters 3a-q in 84-93% yields were developed. The structure - aroma correlation of 2 and 3a-q was studied.
