The cleavage of the P O bond in the title reaction is an unusual finding – this bond, however, is still generally considered as energetically preferred. The course of the reaction is explained on the basis of an MNDO energy hypersurface by entropy-favored dissipation of the activation energy stored in the “chemically activated” isomerization intermediate (H3C)2POH.
