Abstract 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
