    摘要: A process for preparing butenyl ethers of the formula I CH3—CH═CH—CH2—OR  I by reacting butadiene or butadiene-containing hydrocarbon streams with alcohols of the formula II ROH  II at elevated temperature and superatmospheric pressure in the presence of transition metal complexes containing ligands of compounds of elements of group V of the Periodic Table of the Elements to form an isomer mixture of butenyl ethers of the formula I and butenyl ethers of the formula III CH2═CH—CH(OR)—CH3  III and, optionally, isomerizing the butenyl ethers of the formula III to butenyl ethers of the formula I, where R is as defined in the specification and the catalyst used is a complex of a transition metal of group VIII of the Periodic Table of the Elements with ligands of the formula IV where M is an iron, cobalt, nickel, or ruthenium atom, X is a bridge and where n, y and R1-R6 are as defined in the specification.
