A variety of terminal alkynes were efficiently converted into the corresponding α-acetoxy ketones through gold-catalyzed intermolecular oxidation in the presence of 8-methylquinoline 1-oxide as the oxidant. The reaction probably proceeds through an α-oxo gold carbene intermolecular O-H insertion.
The reaction of terminal alkynes with PhI(OAc)2: a convenient procedure for the preparation of α-acyloxy ketones

supporting information; experimental part, p. 5578 - 5581 (2011/02/22)
Treatment of terminal alkynes with PhI(OAc)2 in different acids at 70 °C provided the corresponding α-acyloxy ketones in good to excellent yields. A plausible mechanism has been proposed based on the experimental results.
Convenient syntheses of 2-alkyl(Aryl)-4,5-diphenyloxazoles and 2-alkyl(Aryl)-4-phepyloxazoles

The synthetic methods to prepare 2-alkyl(aryl)-4,5-diphenyloxazoles and 2-alkyl(aryl)-4-phenyloxazoles were improved on the basis of a mechanistic study of oxazole formation from α-hydroxy ketones (carboxylic esters of benzoin and phenacyl alcohols). By these methods, seven trisubstituted oxazoles and twelve disubstituted oxazoles of the title compounds were prepared.
Effect of Cationic and Nonionic Surfactants on the Reactions of Phenacyl Bromide with Some Carboxylates
Mishra, M.,Das, B. N.,Sinha, B. K.
, p. 728 - 731 (2007/10/02)
The reaction of phenacyl bromide with sodium salts of aliphatic carboxylic acids has been studied in acetone-water (72:28) mixture in the presence of varying concentrations of cationic detergent, cetyltrimethylammonium bromide (CTAB).The second-order rate
