A novel and efficient heterogeneous gold(I)-catalyzed three-component reaction of aldehydes, alkynes, and orthoformates has been developed that proceeds smoothly in dichloroethane (DCE) at 83 °C in the presence of 5 mol% magnetic nanoparticles-anchored phosphine gold(I) complex (Fe3O4@SiO2-P-AuOTf) and offers a general and practical approach for the preparation of a variety of propargyl ethers with good yields. This heterogeneous gold(I) catalyst can be facilely recovered by simply applying an external magnetic field and recycled at least eight times without any apparent decrease in the catalytic efficiency.
A DDQ-promoted metal-free cross-coupling of 1,3-diarylpropynes with hydroxyl via Sp3 C-H bond activation to form C-O bond

A metal-free coupling reaction between 1,3-diarylpropynes and alcohols/phenols/acids via propargylic sp3 C-H bonds activation and C-O bond formation reaction promoted by DDQ was realized. The reaction afforded series of propargyl ethers, propargyl esters and propargyl ketals.
AuPPh3Cl/AgOTf-catalyzed reaction of terminal alkynes: nucleophilic addition to activated C{double bond, long}O bond

experimental part, p. 6053 - 6056 (2010/03/01)
Terminal alkynes, under Au-catalyzed conditions, react with aromatic aldehyde diethyl acetals, affording propargylation products through C{double bond, long}O bond addition. Furthermore, AuPPh3Cl/AgOTf-catalyzed three-component reaction of alde
