Notes:
The rates of the BECKMANN-CHAPMAN rearrangement of the ketoximpicryl-ethers 1a-1k in 1, 4-dichlorobutane are correlated with parameters describing the bulk of the substituted groups R and R′. From regression analyses it is concluded that the relative rate constants are mainly controlled by steric contributions in the ground state, such as geminal interactions of R with R′ and vicinal interactions of R′ with O—X, and less by inductive effects.Conformational equilibria between (Z)- and (E)-isomers of N-alkyl-N-picryl-amids have been studied by NMR. in several solvents.
