A solution of camphene (300 g) in ethyl bromide (150 g) is saturated with hydrogen chloride at 10-20° and heated under reflux for 6 days at 55°. Most of the ethyl bromide is then removed in a current of dry air, and the isobornyl chloride is filtered off and dried in a vacuum over potassium hydroxide (yield 271 g m.p. 145°). Recrystallization from pentyl alcohol gives material of m.p. 161.5°.

Yields of the primary alkyl acrylates vary somewhat, owing to occasional losses through formation of polymer, but are usually in the range of 85-99%. Some secondary alcohols react very slowly, others readily. The method has been applied to more than fifty alcohols, some of which (with percentage yields) are listed below ethyl, 99% isopropyl, 37% -amyl, 87% isoamyl, 95% -hexyl, 99% 4-methyl-2-pentyl, 95% 2-ethylhexyl, 95% capryl, 80% lauryl, 92% myristyl, 90% allyl, 70% fur-furyl, 86% citronellyl, 91% cyclohexyl, 93% benzyl, 81% (3-ethoxyethyl, 99% /S-(/3-phenoxyethoxy) ethyl (from diethylene glycol monophenyl ether), 88%.

Alcohols can be phosphorylated to phosphoric diesters by ionic phosphoric monoimidazolides in acetone at temperatures of about 50-60 °C over the course of several hours. These imidazolides are generally prepared by reaction of the appropriate phosphate with CDI (see Section 2.2). Reactions with ethyl, -butyl, w-pentyl, -octyl benzyl alcohol and various other alcohols have also been described.[1]...

Several reagents reduce aldehydes preferentially to ketones in mixtures of both. Very high selectivity was found in reductions using dehydrated aluminum oxide soaked with isopropyl alcohol and especially diisopropylcarbinol [755], or silica gel and tributylstamane [756]. The best selectivity was achieved with lithium trialkoxyalumimm hydrides at —78°. In the system hexanal/ cyclohexanone the ratio of primary to secondary alcohol was 87 13 at 0° and 91.5 8.5 at —78° with lithium tris(/er/-butoxy)aluminum hydride [752], and 93.6 6.4 at 0° and 99.6 0.4 at —78° with lithium tris(3-ethyl-3-pentyl-oxy)aluminum hydride [752],... 

Tertiary alcohols are oxidized in water-dioxane-NaOH to alkoxy radicals, wliich fragmentate to ketone and alkyl radicals R- (Eq. (216) ). The relative rate of cleavage decreases with R in the order sec -butyl > isopropyl > ethyl > propyl > pentyl > isobutyl > methyl 46 8). Likewise, the bisulfite adduct of cyclohexanone is converted in 20% yield to 4-hydroxyhexanoic acid lactone (160) and 3-hydroxycyclohexanoic acid lactone (161) by anodic fragmentation (Eq. (222) ) 469 ... 

The following example illustrates this point. We shall see (Sec. 16.5) that the neopcntyl cation is particularly prone to rearrange to the more stable ten-pentyl cation. Neopentyl bromide reacts (slowly) with ethoxide ion by an 8 2 mechanism to yield neopentyl ethyl ether it reacts (slowly) with ethyl alcohol by an SnI reaction to yield almost entirely rearranged products. 

When starch is the starting material, there is obtained, in addition to ethyl alcohol, a smaller amount of fusel oil (German Fusel, inferior liquor), a mixture of primary alcohols mostly isopentyl alcohol with smaller amounts of /2-propyl alcohol, isobutyl alcohol, and 2-methyl-1-butanol, known as active amyl alcohol amyl pentyl). 

Esters are responsible for the flavors and aromas of many fruits. Pentyl pentanoate smells like ripe apples. Ethyl butanoate has the aroma of pineapples, and 3-methylbutyl acetate smells like bananas although it imparts a pear flavor to foods. Most natural aromas and flavors are mixtures of esters, aldehydes, and alcohols.

Oxocyclohexylidene)triphenylphosphorane 456 [5-(Ethoxycarbonyl)pentyl]triphenyl-phos-phonium iodide (42 g) is added to a solution of potassium (3.4 g) in tert-butyl alcohol (300ml), and the mixture is heated under reflux for 12 h and then evaporated in a vacuum. The residue is shaken with chloroform and water. The chloroform layer is separated and dried, and the ylide is precipitated by ethyl acetate it has m.p. 243-245° (22.1 g, 79%).
