Dissociation energy of organic

The NIST Chemistry WebBook contains thermochemical data, reaction thermochemistry data, spectra, spectroscopic data, ion energetics data, thermophysical property data [150]. Several compilations of enthalpies of vaporization and sublimation measured by different means can be foxmd in the literature [3,151-154]. A compilation of bond dissociation energies of organic compounds has recently been published by Luo [155].

Other factors (e.g. polarization, hybridization, conjugation, hyperconjugation, non-bonding electron repulsion) are in play as well as will be discussed in more detail in the subsequent parts of this hook.

Studies of bond dissociation energies of organic polyatomic molecules led me to conclude that the weakest bond in toluene is the PhCH2 H. Indeed, pyrolysis of toluene carried out in a flow system at pressures of 5-10 torrs resulted in its dissociation into a thermally stable benzyl radical and a hydrogen atom. Thus, dibenzyl and H2 were the main products of the decomposition.

The predominant species observed in SIMS spectra are singly charged atomic and molecular ions [51], However, inorganic and organic cluster ions can also be formed. If the sample consists of a simple single-component metal, then clusters such as M, M, etc., are observed in addition to M+ [52], Oxidation of the metal results in formation of MO ", MO/, M Oll", etc. The relative yield of MO+ to M+ depends on the bond dissociation energy of the oxide [52], For a two-component, oxidized metal, clusters of the type M/", M N, MjO, and M N O/ are observed [51]. 

Three- and pentacoordinate organic phosphorus compounds can be oxidized through a free radical Arbuzov reaction, i.e., formation and p-scission of a phosphoranyl radical (Scheme 24). The P-scission is regioselective homolysis occurs on a ligand located in an equatorial site. Both a- and P-scissions are strongly dependent on the strength (bond dissociation energy) of the cleaved...

Knowledge of homolytic bond dissociation energies (BDEs) is critically important for understanding radical chemistry. The bond energies of organic compounds have been reviewed extensively, but we will use recommended R-H BDE values for organic compounds given in a recent excellent... 

Although we will deal with organic radicals in solution, it is worth mentioning that the reactivity of atoms and small organic radicals with silanes in the gas phase has been studied extensively. For example, the bond dissociation energies of a variety of Si-H bonds are based on the reaction of iodine or bromine with the corresponding silanes.1...
