Imidoylketene-alpha-oxoketenimine and alpha-oxoketene-alpha-oxoketene rearrangements. 1,3-Shifts of substituted phenyl groups

1,3-Phenyl shifts interconvert imidoylketenes 1 and alpha-oxoketenimines 2 and, likewise, alpha-oxoketenes 3 automerize by this 1,3-shift. These rearrangements usually take place in the gas phase under conditions of. ash vacuum thermolysis. Energy profiles calculated at the B3LYP/6-31G(d, p) and B3LYP/6311 + G(3df,2p)//B3LYP/6-31G(d,p) levels demonstrate that electron donating substituents ( D) in the migrating phenyl group and electron withdrawing ones ( W) in the non-migrating phenyl group, can stabilise the transition states TS1 and TS2 to the extent that activation barriers of ca. 100 kJ mol(-1) or less are obtained; i.e. enough to make these reactions potentially observable in solution at ordinary temperatures. The calculated transition state energies Delta G(TS1) show an excellent correlation with the Hammett constants sigma(p)(W) and sigma(p) +(D).
