The reaction of terminal alkynes with PhI(OAc)2: a convenient procedure for the preparation of α-acyloxy ketones
摘要:
Treatment of terminal alkynes with PhI(OAc)(2) in different acids at 70 degrees C provided the corresponding alpha-acyloxy ketones in good to excellent yields. A plausible mechanism has been proposed based on the experimental results. (C) 2009 Elsevier Ltd. All rights reserved.

corresponding α-acetoxy ketones throughgold-catalyzedintermolecular 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. A variety of terminal alkynes were efficiently converted into the corresponding α-acetoxy ketones throughgold-catalyzedintermolecular oxidation in the presence of 8-methylquinoline
