Journal ArticleDOI
Pd-catalyzed copper-free carbonylative Sonogashira reaction of aryl iodides with alkynes for the synthesis of alkynyl ketones and flavones by using water as a solvent.
TL;DR: The Pd-catalyzed copper-free carbonylative Sonogashira coupling reaction to synthesize alkynyl ketones from terminal alkynes and aryl iodides was achieved by using water as a solvent and was successfully applied to the synthesis of flavones.
Journal ArticleDOI
Regiospecific Carbonylative Annulation of Iodophenol Acetates and Acetylenes To Construct the Flavones by a New Catalyst of Palladium−Thiourea−dppp Complex
TL;DR: Regiospecific carbonylative annulation of o-iodophenol acetates and acetylenes mediated by palladium-thiourea-dppp complex in the presence of base at 40 degrees C under a balloon pressure of CO generates diversified flavones in high yields.

Transition‐Metal‐Free Intramolecular Ullmann‐Type O‐Arylation: Synthesis of Chromone Derivatives
Jie Zhao,Yufen Zhao,Hua Fu +2 more
TL;DR: The unexpected transition-metal-free intramolecular Ullmann-type O-arylation leading to chromone derivatives is reported, which shows that transition- metal catalysts seem to be necessary in O-arylations.
