Abstract

A polystyrene‐(benzotriazole)(triphenylphosphine)gold(I) [Btz⋅Au(I)PPh~3~] resin, representing the first polystyrene‐immobilized homogeneous gold(I) complex, was conveniently prepared, and showed remarkable catalytic activities and recyclability in three model transformations, including the tandem 3,3‐rearrangement and Nazarov reaction of an enynyl acetate, the cyclization of a 1,6‐enyne, and the rearrangement of an alkyne‐furan.
