What is Thermochemistry of Carbene and Nitrene Rearrangements about?

Thermochemical estimates for aromatic carbenes and nitrenes and their interconversions are reported and allow a unifying explanation of the majority of the experimental data published to date. Chemical activation is a very important, but hitherto ignored factor in these rearrangements. This has given rise to several misinterpretations in the literature, which are now corrected. The rearrangements of aromatic carbenes and nitrenes are being extensively discussed in the current literature. It is the purpose of the present paper to present thermochemical estimates' which support recent semi-empirical calculations' and clarify the mechanistic speculation on the subject. Heat of formation data and the means of their calculation are indicated in Table . ## 1. The phenyicarbene-cycloheptatrienylidene and related rearrangements The interconversion of phenylcarbene (1) and cycloheptatrienylidene (2) occurs in the gas-phase at 250-8000,' but even the direction of the equilibrium is a matter for conjecture.'PM Consider the forward reaction: From the values in Table the calculated enthalpy change for reaction (1) is co + 13 kcal/mol for the triplet species, in good agreement with three differ
