Figure 2.11 Li+ + F steric repulsions, showing total (solid) and individual orbital contributions (dashed) for filled—filled orbital interactions near Req 1.6 A.

For Li—F, the quantal ionic interaction can be qualitatively pictured in terms of the donor-acceptor interaction between a filled 2pf. orbital of the anion and the vacant 2su orbital of the cation. However, ionic-bond formation is accompanied by continuous changes in orbital hybridization and atomic charges whose magnitude can be estimated by the perturbation theory of donor-acceptor interactions. These changes affect not only the attractive interactions between filled and unfilled orbitals, but also the opposing filled—filled orbital interactions (steric repulsions) as the ionic valence shells begin to overlap.

Figure 10.15 Backside attack by a nucleophile. Now HOMO-LUMO interaction is possible, and the transition state is stabilized. (As in the H- + F2 process, Figure 10.13, there will also be a smaller HOMO-HOMO interaction here. Because it is a filled-filled interaction, it will not alter the energy.)...

Another application is to bimolecular SN2 and S 2 substitutions. Recall from Chapter 4 (pp. 174 and 205) that the nucleophilic reaction prefers backside attack by nucleophile on substrate whereas the electrophilic reaction prefers frontside attack. Figure 10.14 shows the appropriate frontier orbitals for frontside attack by a nucleophile. The nucleophile, symbolized by N, is the donor, and the C—X bond is the acceptor. The symmetries of the nucleophile HOMO and the C—X LUMO do not match (13) therefore only the filled-filled HOMO-... 

The dependence of solubility on pressure requires an understanding of the equation of state of hydrothermal solutions saturated with quartz. Systematic P-V-T studies have been conducted.(77) Fig. 4(77) summaries some of this data. As can be seen, behavior is qualitatively like that for pure H2O but with pressures substantially reduced. Pressure in hydrothermal quartz synthesis is established by the initial fraction of the vessel volume (% fill) filled with (OH) solution at the beginning of the growth run. 

Kass argued that 2r is stabilized by an interaction between the radical orbital on Cx and ct(C2-C3) orbital. This allows the radical to delocalize, especially onto C3. As listed in Scheme 3.2, the spin densities at Cj and C3 are quite similar, 0.59 and 0.34, respectively. A further manifestation of this delocalization is the short Cl -C3 distance (1.493 A) in 2r compared to that in 2 (1.512 A). This orbital interaction is negligible in the anion 2cb because it is a filled-filled interaction. The charge density is much more localized onto Cj for 2a than is the spin density for 2r. Consequently, 2r is more stable than expected, leading 2 to have a smaller BDE than anticipated. 2 thus has the acidity of an acetylene but the bond energy of methane. ... 

The first and most influential molecular-orbital calculation on metal-alkynyl complexes is that of Kostin and Fenske, who applied the Fenske-Hall method to the complexes FeCp(C=CH)(PH3)2 and FeCp-(C=CH)(C0)2 (11). They concluded that the M-CCH bonds in these complexes are nearly pure a in character. The large energy gap (ca. 15 eV) between the occupied metal orbitals and ir (C=CH) levels severely limits the ir-accepting quality of the latter, with the total electron population for the pair of tt orbitals being 0.22 e for FeCp(C=CH)(PH3)2 and 0.14 e" for FeCp(C=CH)(CO)2. The filled ir(C=CH) orbitals, in contrast, mix extensively with the higher-lying occupied metal orbitals these filled-filled interactions result in the destabilization of the metal-based orbitals. The HOMOs of both complexes possess substantial coefficients at the alkynyl jS-carbon this was noted to be consistent with the alkynyl-localized reactivity of these complexes.
