The modes of addition shown in Figure 6.3 are similar to those shown in Figure 6.2 and are consistent with extant mechanistic work [6,9] they accurately predict the identity of the slower reacting enantiomer. It should be noted, however, that variations in the observed levels of selectivity as a function of the steric and electronic nature of substituents and the ring size cannot be predicted based on these models alone more subtle factors are clearly at work. In spite of such mechanistic questions, the metal-catalyzed resolution protocol provides an attractive option in asymmetric synthesis. This is because, although the maximum possible yield is 40 %, catalytic resolution requires easily accessible racemic starting materials and conversion levels can be manipulated so that truly pure samples of substrate enantiomers are obtained. 

Percent yield is the actual yield (how much was actually formed in the reaction) divided by the theoretical yield (the maximum possible amount of product formed) times 100%. 

Theoretically the maximum possible yield under these conditions of temperature and pressure would be 35 4 cubic feet per lb of silicol of this purity... 

The maximum possible yield of one enantiomer in a kinetic resolution process is 50%. 

In addition, it is important to note that the phase behavior of PHIP NMR signals differs substantially from that in standard NMR experiments. For normal NMR spectroscopy, a 90° pulse renders the maximum possible signal intensity, while a 180° pulse gives no intensity at all. This is not true for PHIP spectra In PHIP NMR, the maximum signal intensity is achieved by a 45° pulse a 90° pulse is here the zero-crossing (like 180° in standard NMR, yielding minimum intensity). 

The experiments which yielded the diffusion coefficients for acetaminophen in PNIPAAm gel in Fig. 16 also yielded the corresponding partition coefficients. While the diffusion coefficients fit theory, the partition coefficients as plotted in Fig. 18 do not at all. In fact, a trend opposite to theory is observed as the partition coefficients are seen to increase as the gel swelling decreases. In fact, above the transition temperature of the gel, at 35 °C, the partition coefficient is seven times the maximum possible size exclusion coefficient, 1. This implies the dominance of hydrophobic effects over steric effects, since acetaminophen is a relatively small, nonionic but hydrophobic solute, and while the gel mesh size shrinks with increasing temperature, its level of hydrophobicity increases with temperature. 

Electron transfer from the excited states of Fe(II) to the H30 f cation in aqueous solutions of H2S04 which results in the formation of Fe(III) and of H atoms has been studied by Korolev and Bazhin [36, 37]. The quantum yield of the formation of Fe(III) in 5.5 M H2S04 at 77 K has been found to be only two times smaller than at room temperature. Photo-oxidation of Fe(II) is also observed at 4.2 K. The actual very weak dependence of the efficiency of Fe(II) photo-oxidation on temperature points to the tunneling mechanism of this process [36, 37]. Bazhin and Korolev [38], have made a detailed theoretical analysis in terms of the theory of radiationless transitions of the mechanism of electron transfer from the excited ions Fe(II) to H30 1 in solutions. In this work a simple way is suggested for an a priori estimation of the maximum possible distance, RmSiX, of tunneling between a donor and an acceptor in solid matrices. This method is based on taking into account the dependence... 

With the maximum possible value of 7 - 1, we obtain = 3 x 10 10s yielding the upper limit for 7055 as 0.03. From Equation 7 and Figure 2 we have 7 =... 

To achieve a faujasite-type product with the maximum 0-NNN sites requires a 10 SiC>2/Al203 product with ordered distribution of Al3 in the T-sites. This is die material I choose to designate type Z faujasite. In terms of die unit cell, this is 32A13+/UC (32/(192-32)=0.2). It seems unlikely that stabilization or extraction treatments will yield such a product The optimum zeolite reported by Pine, et al. as 24A13+/UC is at least 25% off the maximum possibly due to a significant concentration of Si(OAl)2 in the parent zeolite. 

Considering Equation (4), it is clear that one has to operate a galvanic cell at the maximum possible cell voltage in order to maximize the electric energy yield. As shown previously (Figure 3.1.6), the maximum value of U is the equilibrium electrode potential difference E or E°. Thus, one may formulate the fundamental relationship between chemical and electric energy ... 

So, instead of being acylated, the starting anion is protonated. This side-reaction could reduce the maximum possible yield in the acylation reaction to 50% half the starting material forms the product by acylation, while the other half simply deprotonates the product. How is this to be avoided ...
