Kharasch, M. S. J. Res. Natl. Bur. Stand. 1929, 2, 359-430. It is unclear from the tables of thermodynamic data if the Kharasch measurement is a gas-phase enthalpy. If it is a condensed-phase measurement, then the heat of vaporization of methyl isobutyrate must be added to the measured value of - 117.3 kcal/mol, which would essentially make the Engel and Kharasch numbers equal.

A similar "negative activation energy" has been seen, and a similar explanation (reversible formation of a dissociable intermediate) offered, for a carbene/alkene cycloaddition in Turro, N. J.; Lehr, G. F.; Butcher, J. A., Jr.; Moss, R. A.; Guo, W. J. Am. Chem. Soc. 1982, 104, 1754-1756.

3• (1a) and the tertiary radical 3-P will be weak. Formation of such a bond would reduce the efficiency of 1a as a chain transfer catalyst, as the resulting alkyl complex 5 cannot be an intermediate in formation of the hydride 2a (5 would have no vacant coordination site and thus be unable to undergo β-hydrogen elimination). Weak interaction between the metalloradical 1a and the carbon-centered radical 3-P can. however, contribute to the formation of the cage in Scheme 6.

Reversible formation of a Co-C bond has been observed with Co(II) chain transfer catalysts and the α-methylbenzyl radical 4 in styrene polymerization, but it is insignificant with the isobutyryl radical 3 in MMA polymerization.
