Decanoic acid chloride

Product isolation is very simple as only the solvent has to be removed after separation from the polymer. The polymer can be returned to the active chlorinating agent by reaction with carbonyl chloride. A variation of this procedure does not require polymer-bound phosphorus halide but uses Lewis acid-Lewis base complexes between anion-exchange resins, such as Amberlite IRA 93, and phosphorus pentachloride (equation 4). Again, isolation of the resultant acid chloride is simple and the exhausted polymer can be regenerated for further use by simply washing it with aqueous acidic and basic solutions. Yields range from 51 % for crotonic acid chloride to 86% for decanoic acid chloride.

D-Phenyl propionates of methyl esters of racemic hydroxy acids were prepared by Hammarstrom and Hamberg [190] and used for the separation of enantiomers of these compounds on QF-1. The separation was successful with methyl 3-, 15-, 16- and-17-hydroxyoctadecanoates, whereas diastereoisomers of methyl 4-, 7- and 13-hydroxyocta-decanoic acids were not separated. The derivatives were prepared at room temperature reaction of the ester of the hydroxy acid with D-2-phenylpropionyl chloride in the presence of pyridine for 2 h. 

In the extraction of Mn(II) from ammonium chloride solution with decanoic acid benzene, Bartecki et al. (11) reported that the prevailing species in the organic phase was a dimeric complex, Mn2A4(HA)4, in addition to a small amount of tri- and tetramers. The monomeric extracted species MnA2(HA)2, found in decane (39), seems unlikely.

A single acyl group has been introduced into P-cyclodextrin, either at a 2- or a 3-position, by exposure to benzoyl- or a- or P-naphthoyl chloride in alkaline aqueous acetonitrile. A Lipid A disaccharide esterified with (5)-3-hydroxytetra-decanoic acid and a Lipid A monosaccharide carrying a fluorinated JV-acyl group are referred to in Chapters 3 and 9, respectively. 

The diversity associated with silyl protecting groups as well as the chemical conditions available for their removal makes them attractive alternatives to benzyl protection of the hydroxy groups of either D- or L-tartaric acid derivatives. O-isopropylidene-L-threitol (37) is mono-protected with er -butyldimethylsilyl chloride to furnish 266, which is converted in three steps to the nitrile 267. Reduction with DIBAL and Wittig olefination followed by desilylation with fluoride and Swern oxidation of the resulting alcohol provides aldehyde 268, which reacts with methyl 10-(triphenylphosphorane)-9-oxo-decanoate (269) to afford enone 270. Reduction of 270 with subsequent preparative TLC and acetal hydrolysis furnishes (9R)-271 and (9 S)-272, both interesting unsaturated trihydroxy Cig fatty acid metabolites isolated from vegetables [91] (Scheme 62). 

Esterification reactions readily occur in ionic liquids. A simple example is the reaction of acetic, decanoic and octadecanoic acid with alcohols such as methanol, 1-butanol or 1-octanol. Here, Tang et al. used the ionic liquid [H-MIM][BF4] (this is a simple mixture of 1-methylimidazole and tetrafluoroboric acid) as a solvent and catalyst for the reaction [189]. Singer and coworkers have shown that benzoyl chloride reacts with ethers to give alkyl benzoates [190] in chloroaluminate(iii) ionic liquids. This reaction results in the acylative cleavage of ethers, and a number of reactions with cyclic and acyclic ethers were investigated in the ionic liquid [EMIMjl-AICI3 (X = 0.67). Two examples are shown in Scheme 5.2-79. 

Vinyl acetate is relatively inexpensive and is readily copolymerized with vinyl chloride, ethylene, acrylates and methacrylates. The monomer is a colourless, flammable liquid with an initial pleasant odour, which on exposure becomes irritating. One of the major disadvantages of vinyl acetate-based copolymers is their poor hydrolytic and UV stability. This was shown to improve when copolymerized with vinyl esters of versatic acid [18]. Copolymers of vinyl acetate with the vinyl esters of versatic acid have been used in Europe for the last quarter-century. In the US similar monomers were introduced in the past five years, two of which are illustrated in Table 6.1, namely, vinyl pivalate and vinyl neo-decanoate. More details of the copolymerization of these monomers with vinyl acetate is given in Chapter 16. 

These are numbered with CO2H=1 when named as -oic acids or by trivial names. The three trivial names of acids beginning wdth capr- should be superseded by the systematic names (caproic=hexanoic, caprylic=octanoic, capric=decanoic). For acids named by the carboxylic acid method, e.g. heptane-1,4,7-tricarboxylic acid or 3-carboxypropylammonium chloride, the CO2H group is treated by the normal methods for suffixes and prefixes (see p. 48).
