For each of four radicals (methyl, octyl, 2,2-dimethylhexyl, and 1,1-dimethyl-nonyl) considered, the plot of log(kBrAci) against 1/T is linear, as it must be. It turns out that these four lines cross at nearly the same temperature, as shown in Fig. 10-7. The phrase isoselective (is) temperature has been coined to designate the approximate temperature at which the four lines intersect. In this sequence T-,s = 50 10 °C. At 0 °C, the methyl radical is the least selective at 130 °C it is the most selective. At TIS all four radicals show the same selectivity toward BrCCl3 and CCI4.

Scheme 8.2. Anodic oxidation of alkanols catalysed by bromide ion and methyl octyl...

A combination of bromide ions and methyl octyl sulphide is able to oxidise secondary alcohols at the potential necessary to fonn bromine. Conversion of the alcohol to the ketone follows the Scheme 8.2 and uses an undivided cell with benzo-nitrile as the solvent containing 2,6-lutidine as base and tetraethylamnionium bromide. The reaction occurs using a platinum anode at 1.1 V vs-, see [28], Thio-anisole alone, in absence of bromide, will function as a catalyst for the oxidation of secondary alcohols but in these cases a more positive anode potential of 1.5 V vs. see is needed to oxidise the thioether [29]. 

Another potentially important fermentation is that producing butyric acid. The process is used industrially on only a small scale at present and details have not been disclosed. Many derivatives of butyric acid are used industrially the benzyl, methyl, octyl and terpenyl esters are used in the perfumery and essence trade and amyl butyrate, bornyl and isobornyl butyrates have been described as plasticizers for cellulose esters. Moreover vinyl butyrate is a possible ingredient of polymerizable materials. The mixed acetic and butyric acid esters of polysaccharides are also coming into favor. Cellulose acetate butyrate is marketed as an ingredient of lacquer and is less inflammable than the pure acetate. Dextran (see below) acetate butyrate may have similar uses. 

In CC14 and tetrachloro ethylene, the products identified were phosphinic acid (1), phosphinylacetic acid (5), and methyl(octyl)(phenyl) phosphine oxide (3) (40, 41). But gas chromatography alone was not able to identify 50% of the unknown compounds. 

It should be noted that functionalised diacetylene monomers have also been used for coupling reactions with haloarenes. By reacting diacetylene-substituted p-aminoanilines [135] and diethynyl(methyl)( -octyl)silane [136] with diiodoarenes, polyamides and polysilanes have been prepared, respectively.

The synthesis of both isomers of a given sulfoxide can be achieved via the Orsay route by permutation of the R, and R2 in organometallics involved in the two substitution steps, and has been done in the synthesis of o.p. R and 5 methyl octyl sulfoxide and benzyl ethyl sulfoxide. This is possible only when both R, and R2 are either small or bulky—when one of the groups is small and the other bulky, the permutation leads to the same sulfoxide. 

Chiral sulfoxides. The Sharpless reagent lor asymmetric epoxidation also effects asymmetric oxidation of prochiral sulfides to sulfoxides. The most satisfactory results are obtained for the stoichiometry Ti(0-(-Pr)4/L DET/H20/(CH,),C00H = 1 2 1 2 for I equiv. of sulfide. In the series of alkyl p-tolyl sulfides, the (R)-sulfoxide is obtained in 41-90% ee the enantioselectivity is highest when the alkyl group is methyl. Methyl phenyl sulfide is oxidized to the (R)-sulfoxide in 81% ee. Even optically active dialkyl sulfoxides can be prepared in 50-71% ee the enantioselectivity is highest for methyl octyl sulfoxide.
