, p. 106350 - 106354 (2016/01/09)
The first intermolecular addition reaction of aryloxyl radicals to CC bonds was disclosed, which can afford biologically important chromone scaffolds via a PhNMe3I-catalyzed direct coupling of readily available salicylaldehydes and activated internal alkynes in only one step, and can tolerate a range of catalytically reactive functional groups.
A green and rapid approach for the stereoselective vinylation of phenol, thiol and amine derivatives in water

supporting information; experimental part, p. 2851 - 2858 (2011/11/06)
The stereoselective formation of C-O, C-S and C-N bonds by the reaction of phenols, thiols and amines with activated alkynes is described. The reactions are successfully conducted in water with excellent yields at room temperature. The lack of organic sol
Reaction between ortho-hydroxy aromatic aldehydes and dialkyl acetylenedicarboxylates in the presence of silica gel in solvent-free conditions

, p. 3181 - 3189 (2008/02/12)
A two-component condensation reaction between an ortho-hydroxy aromatic aldehyde and an electron-poor acetylenic ester efficiently provides fully substituted electron-poor aryl vinyl ethers and chromenes in a one-pot reaction in the presence of silica-gel in solvent-free conditions.
