Wang and Stack (211) reported seven four-coordinate bis(phenolato)copper(H) complexes that were chemically one-electron oxidized with tris(4-bromo-phenyl)aminium hexachloroantiomonate to the corresponding EPR silent (phe-noxyl)copper(II) species. These compounds are schematically shown in Fig. 28. In a subsequent paper (212), these authors showed by Cu K-edge XAS that oxidation of the neutral species to the monocation is ligand centered with formation of (phe-noxyl)copper(II) species, in excellent agreement with similar experiments on GO. 

It is noteworthy that similar products are also obtained from oxidation of enol silyl ethers with two equivalents of tris(p-bromo-phenyl)aminium hexa-chloroantimonate which is known to oxidize electron-rich double bonds to...

The reaction rate has also been greatly increased by the addition of a one-electron oxidant tris-(4-bromophenyl)aminium hexafluoroantimonate Ar3N SbF6 (Ar = p-bromo-phenyl).444 This reagent converts the substrate to a cation radical, which undergoes ring expansion much faster.445...

The discovery of 1 -aryl-1 -dimethylamino-cyclohexanes resulted from a surrey of compounds in which aromatic and basic features, both critical structural requirements of opioid analgesics, but usually separated by two or three carbon atoms, are linked to the same quaternary carbon. The synthesis of these compounds yielded a series of highly potent opioids (e.g. 1-Benzyl-4-(4-bromo-phenyl)-4-dimethylamino-cyclohexanol), however none of them are in clinical use (Lednicer et al., 1981). 

To give an impression of the nature of useful experimental results, some flow birefringence measurements which were obtained on a solution of polystyrene in methyl 4-bromo-phenyl carbinol, are reproduced in Figs. 1.2 and 1.3. The concentration of the solution was 2 wt. percents, measuring temperatures are indicated in the figures. The special polystyrene used was a well-known sample of anionically polymerized polystyrene, viz. S 111, provided by the courtesy of Dow Chem. Corp. Its molecular weight is 224,000. The indicated solvent is, at 18 °C, a 0-solvent and possesses practically the same refractive index as polystyrene itself (32). The measurement results are kindly provided by Daum from his still unpublished work.

Fig. 1.4 gives such a plot, which was prepared by Philippoff (8,9) from his early measurements on a 15 per cent solution of polyisobutylene (P-100) in decalin (measurement temperatures 30 and 50°C). From this figure it is clearly seen that An as a function of p21 is non-linear. In contrast to the above mentioned solution of S 111 in methyl 4-bromo-phenyl carbinol, the solution of the poly-isobutylene P-100 in decalin does not form a second order fluid. However, for the product A n sin 2%, one obtains a beautiful straight line. The stress-optical law seems to hold also for this more general type of fluid. ...

The data quoted in these figures were obtained on solutions of Taps. No. 5 and S 111 in methyl (4-bromo-phenyl) carbinol. The 0-temperature of these systems is 18° C. In Table 3.2 the intrinsic viscosities of both samples are quoted for four temperatures. The solvent viscosities and densities are given in the lowest two rows. 

This is very remarkable in view of the enormous difference of intrinsic viscosities in methyl (4-bromo-phenyl) carbinol and in bromo-benzene.
