Unsaturated ethers are prepared through the reaction of C4 to C6 aliphatic conjugated diolefins with a monohydroxy alcohol in the presence of a catalyst system based upon zero valent nickel. The preferred catalyst system is made up of a zero valent nickel material, a phosphine or isonitrile activator and further, if desired, an inorganic or organic base cocatalyst. The reaction is conducted at moderate temperature and pressure conditions. The unsaturated ethers can be catalytically hydrogenated to useful ether solvent media.
