Komori and Nonaka132,133 electrochemically oxidized methyl, isopropyl, n-butyl, isobutyl, r-butyl and cyclohexyl phenyl sulfides (108) and cyclohexyl p-tolyl sulfide (109) to their sulfoxides using a variety of polyamino acid-coated electrodes to obtain the range of e.e. values shown in parentheses. The highest enantiomeric purities were obtained using an electrode doubly coated with polypyrrole and poly(L-valine), an electrode which also proved the most durable of those prepared. 

The lithio-derivative derived from cyclohexyl phenyl sulfone underwent 1,2-addition to cyclohexenylideneacetaldehyde or cinnamaldehyde to give the corresponding / -hydroxysulfones387. Reactions of 2,2-dimethyl-4-lithio-1,3-oxathiane 3,3-dioxide 308... 

One other reaction deserves mention. From bis(cyclooctadiene)nickel and butadiene (31), and in the presence of an isocyanide (RNC, R = cyclohexyl, phenyl, tcrt-butyl) two organic oligomeric products are obtained, 1 -acylimino-11 -vinyl-3,7-cycloundecadiene and 1 -acylimino-3,7,11 -cyclo-dodecatriene. In each, one isocyanide has been incorporated. An analogous reaction with carbon monoxide had been reported earlier. The proposed mechanism of these reactions, via a bis-7r-allyl complex of nickel, is probably related to the mechanism described for allylpalladium complexes above. 

Sila-procyclidine, (cyclohexyl)phenyl[2-pyrrolidin-l-yl]silanol, may be prepared by hydrolysis of the corresponding methoxysilane (220) and is interesting in that it can form two types of hydrogen-bonded structure depending on whether it is enantiomerically pure or a racemate. In the racemate, the compound forms centrosymmetric dimers of (R)- and (S)-configuration molecules with an 0---N distance of 1.791 A. In the pure (R)-compound, however, the molecules are linked into infinite chains via intermolecular 0-H---N hydrogen bonds (0---N distance 2.792 A) (221), again similar to those in (2-morpholinoethyl)diphenylsilanol shown in Fig. 3.

Cyclohexyl phenyl ketone was used by Johnson et al. (3) to photocure intermediates for three-dimensional articles using rapid prototyping techniques. The product exhibited stable tensile properties over time. 

Hydrophobic sorbents including octadecyl, octyl, diphenyl, cyclohexyl, phenyl, butyl, ethyl, methyl, and copolymers of styrene and divinylbenzene can be applied for retaining nonpolar to medium polar analytes. In this list, the styr-ene-divinylbenzene copolymer phases such as PRP-1 and XAD-2 are the most nonpolar phases, while the methyl phase is the least nonpolar one. The analytes are adsorbed onto the hydrophobic materials by means of van der Waals interactions and, to some extent, by hydrophobic bonding or dipole-dipole interactions. 

The copolymerization of isocyanides, such as cyclohexyl, phenyl, p-toluyl and (r-toluyl—singly with diazomethane (6), or as mixtures of two isocyanides (7)—has been reported. These products are largely insoluble in common organic solvents but are dispersed in dichloroacetic add. Millich and Wang copolymerized sec-butyl isocyanide with a-phenylethyl isocyanide, and obtained a copolymer sparingly soluble in common solvents (8). Recently, Millich and Chenvanij copolymerized a phenylethyl isocyanide with methyl a-isocyanopropionate, and obtained copolymers which have solubilities suitable to conventional solution characterization methods (8,9).
