An efficient and practical synthesis of α-phenylthio ketone through gold-catalyzed intennolecular oxidation of phenylacetylene and substituted aryl(benzyl) allylic sulfides was developed. The reaction scope is fair...
A convenient method for the chlorination in allylic position was developed by using the aqueous solution of sodium hypochlorite(2%_5% active chlorine) and an acid as chlorination reagent in a diphase system. The metho...
