A noncyclic sulfuranyl dioxide anion, (CF3)3S02 (44) of lO-S-5, was prepared in the reaetion of Ph0S02CF3 with CF3SiMe3 and F . The anion is analogous to the intermediate postulated for an assoeiative C-nueleophilic attack at the sulfonyl sulfur.

Cmde diketene obtained from the dimeriza tion of ketene is dark brown and contains up to 10% higher ketene oligomers but can be used without further purification. In the cmde form, however, diketene has only limited stabHity. Therefore, especiaHy if it has to be stored for some time, the cmde diketene is distiHed to > 99.5% purity (124). The tarry distiHation residue, containing trike ten e (5) and other oligomers, tends to undergo violent Spontaneous decomposition and is neutralized immediately with water or a low alcohol. Ultrapure diketene (99.99%) can be obtained by crystallization (125,126). Diketene can be stabHized to some extent with agents such as alcohols and even smaH quantities of water [7732-18-5] (127), phenols, boron oxides, sulfur [7704-34-9] (128) and sulfate salts, eg, anhydrous copper sulfate [7758-98-7]. 

COSY, HMQC, HMBC, and HSQC-TOCSY NMR spectra. The relative stereochemistry of each of the piperidine rings in 21 was estabhshed by analysis of NMR and NOESY spectra. However, the authors have not obtained experimental data to relate the relative stereochemistry of each piperidine moiety to the other. They suggested the relative stereochemistry indicated in 21, based on the Baldwin and Whitehead biogenetic proposal [24] (see below) and also by comparison with data for haliclonacyclamine E (5) and arenosclerin A (14). 

Note that in weakly polar (.e < 5) and nonpolar solvents, it is impossible to blow off oxygen adsorbed on ZnO film with an inert gas hydrogen, nitrogen, etc.), similar to the case of gas or saturated vapour phase (polar liquid at any e) at room temperature, i.e., under the conditions, where f = 1, and no liquid layer is condensed on the film.

It may be recalled that it was deduced from the similarity solution for flow over a flat plate that Six) = 5/jRex. The difference between the value of the coefficient in this equation, i.e., 5, and the value in Eq. (3.136), i.e., 4.64, has no real significance since, in deriving the similarity solution result, it was arbitrarily assumed that the boundary layer thickness was the distance from the wall at which u became equal to 0.99 m. 

Assuming that the ion is situated in water, one has e p = 1.8, e = 5, and e = 80. Using these values and Eq. (4), one may conclude that the largest role in such an interaction is played by the electronic polarization corresponding to the first term in parentheses in Eq. (4), which is equal to 0.44. The second term, corresponding to atomic polarization, is equal to 0.36. The role of the orientational polarization is the smallest (0.19). 

Option 2 of the ICH document allows for the use of a "... cool white fluorescent lamp as defined in ISO 10977 1993 (E), (5)" and "A near UV fluorescent light". This combination of lamps presents certain problems. We have previously noted the mix up of lamp types (old vs. new phosphor) and the "Tonnesen gap." In addition to these problems, there is the question of whether the exposure should be with both lamps illuminating at the same time, and if not, then which lamp should be used for the first exposure.
