The reaction of a pseudo-ozonide metallacycle involving one carbonyl group with a spiranic steric arrangement.Strangely the second carbonyl group of the quinone does not react with an excess of a skew conformation of the metallacycle with the quinone moiety still planar.Reaction with a slight perturbation of the ?-electronic conjugated structure of the quinone, since the C=O bond length of the free carbonyl group does not change.Molecular models suggest the absence of steric hindrance for a second pseudo-ozonide metallacycle involving the para carbonyl group.It is suggested that the lack of reactivity could be of kinetic origin.
