An Eldorado for Homogeneous Catalysis?

A gold rush can occur not only among diggers at the banks of a remote river, but also among chemists in catalytic research laboratories. Gold salts displaying high catalytic activity facilitate domino coupling reactions in C−heteroatom and C−C coupling. Thus, for example, furyl-substituted products 2 are preparatively accessible in one step from three units of allenyl ketone 1.
