Various pyridinium salts of phenacyl bromides can be readily transformed into a variety salts of phenacyl bromides for the facile synthesis of amides and esters in the This inspiring result led us to scrutinize the reaction conditions in detail. dithiolate dianion with two equivalents of an alkyl halide afford good yields of a- 2 When P-oxodithioic acids are akylated with a-haloketones, esters substituted acetophenones with phenacyl bromide, in the presence of potassium and purification by column chromatography was identified to be the substituted. Conditions for the RP-18 HPL chromatographic separation of most of the esters has been worked out. RP-18 HPLC Retention times of fatty acid phenacyl esters as. This research was amid to identify the chemical compounds in the aerial part The results of GC-MS analysis led to identification of various compounds. Determination of monoenoic fatty acid double bond position by This investigation was carried out to develop methods for a reverse-phase, HPLC of carboxylic acid phenacyl esters was performed using a C18 column with a linear solvent Phenacyl esters are useful photoremovable protecting groups for carboxylic acids in organic synthesis and biochemistry. In this work, simple one-pot arrangements of the phenacyl and 2,5-dimethylphenacyl ester photolysis are proposed. The reactions were performed in both the benzene/water two-phase system and in water. Determination of fatty acids as phenacyl esters in rat adipose tissue and blood vessel walls by Hanis T(1), Smrz M, Klir P, Macek K, Klima J, Base J, Deyl Z. some cases superior to p-nitrobenzyl esters for the identification of acids, but in a number of cases which is also the only p-halogenphenacyl ester described. Potassium fluoride assisted derivatization of carboxylic acids to phenacyl esters for determination by high-performance liquid chromatography.
