After further working up there is obtained an oily crystalline residue which is subjected to chromatography on silica gel. The 16a-methyl-6a,9a-difluoro-A -pregnadien-11/3,21-diol-3,20-dione is eluated with ethyl acetatereacted with valeric acid chloride to give the valerate ester.

In the case of some a-alkylbenzyl alcohols like 383 and allethrobne there is a tendency in favour of the formation of the inactive racemate. Fen valeric acid chloride 384 and 3-phenoxy-a-methylbenzyl alcohol 383 produce a diastereomeric mixture, which contains twice as much inactive racemate [816] as racemate of the actual insecticide. Different kinds of reaction types produce different isomeric ratios ... 

Cellulose valerates have been synthesized by conventional methods using valeric anhydride and sulfuric acid catalyst (25,26). Alternatively, the cellulose is activated by soaking in water, which is then displaced by methylene chloride or valeric acid the temperature is maintained at <38° C to minimize degradation. 

The acid chlorides of to-(2-thienyl) substituted butyric (122) and valeric acids (123), as well as the corresponding 5-alkyl-2-thienyl-substituted compounds, undergo internal Friedel-Crafts reaction (SnCl4,CS2) at the 3-position in 70-80% yield, to give the corresponding cyclohexenones (124) and cycloheptenones (125). ...

Acetic acid has been found to react with toluene to form p-methylace-tophenone (Simons et al., 49), to react with benzene to form acetophenone, and to react with phenol to form p-hydroxy acetophenone. Acetyl chloride also formed acetophenone with benzene and acetic anhydride reacted with toluene to form both p-methylacetophenone and 2,4-diace-tyltoluene. Valeric acid reacted with toluene to form p-tolyl-n-butyl ketone. Both benzoic acid and benzoyl chloride reacted with toluene to form p-tolylphenyl ketone. Acenaphthene with either benzoic acid or benzoyl chloride gave 3-benzoylacenaphthene (Fieser and Hershberg,...

The simplest or lowest member of the fatly acid series is formic acid, HCOOH. followed by acetic acid, CHiCOOH. propionic acid with three carbons, butyric acid with four carbons, valeric acid with five carbons, and upward to palmitic acid with sixteen carbons, stearic acid with eighteen carbons and melissic acid with thirty carbons. Fatty acids are considered to be the oxidation product of saturated primary alcohols. These acids are stable, being very difficult [with the exception of formic acid) to convert to simpler compounds they easily undergo double decomposition because of the carboxyl group they combine with alcohols to form esters and water they yield halogen-subslitulion products they convert to acid chlorides when reacted with phosphorus pcntachloridc and Iheir acidic qualities decrease as their formula weight increases.

Acetyl-n-valeric acid has been prepared by the oxidation of 1-methylcyclohexene with potassium permanganate 5 by the oxidation of 2-methylcyclohexanone with chromic oxide and sulfuric acid 6 by the reaction of methylzinc iodide on the ethyl ester of adipic acid chloride and saponification of the ethyl ester of 5-acetyl-w-valeric acid so obtained 7 by the saponification of the ethyl ester of diacetylvaleric acid 2 and through the hydrolysis of ethyl a-acetyl-6-cyanovalerate with boiling 20% hydrochloric acid.3...

Diketones. Vinylmagnesium chloride, in ihe presence of cuprous chloride as catalyst, reacts with a fatty acid or ester to give a 1,6-diketone, usually in rather low yield (5-55%). Thus the reaction as applied to n-valeric acid (I) gives n-telradecane-5,10-dione (2) in 53% yield. 

Two AIBN-type radical polymerization initiators have been synthesized starting from commercial 4,4 -azo-bis(4-cyano)valeric acid (1) (Scheme 1) ACTP 3 -trichlorosilylpropyl-4,4 -azo-bis(4-cyano)valerate (4a) and ACTU 11 "-trichlorosilylundecyl-4,4 -azo-bis(4-cyano) valerate (4b). After thorough drying of the wet diacid 1, it was transformed into its chloride (2) using an excess of phosphorus pentachloride in dichloromethane. Reaction of 2 with the unsaturated alcohols allyl alcohol and 10-undecen-l-ol respectively gave the esters 3 in high yields which in turn led to ACTP (4a) and ACTU (4b) on Pt-catalyzed hydrosilylation. 

The first synthesis of rfZ-deoxynupharidine was reported by Kotake et al. (30). The starting material w as 2,5-lutidine which was made to react with formaldehyde to give the diol XXVII on dehydration, acetylation, and condensation with malonic ester XXVII afforded the diester XXVIII. On hydrogenation and acid hydrolysis XXVIII was decarboxylated to the valeric acid derivative XXIX. After esterification the acid was acylated with 3-furoyl chloride and distilled with soda lime to yield dehydrodeoxynupharidine (XXX), and this on hydrogenation gave dl-deoxynupharidine (II).
