    摘要: A process produces vinyl ether compounds and includes allowing a vinyl ester compound represented by following Formula (1): 1 wherein R1, R2, R3 and R4 are the same or different and are each a hydrogen atom or an organic group, to react with a hydroxy compound represented by following Formula (2):R5OHnullnull(2)wherein R5 is an organic group, in the presence of at least one transition element compound to thereby yield a vinyl ether compound represented by following Formula (3): 2 wherein R2, R3, R4 and R5 have the same meanings as defined above. Such transition element compounds include iridium compounds and other compounds containing Group VIII elements.

    摘要: Enol ethers of the formula I where R1 is an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical which may carry further substituents which do not react with acetylenes or allenes, and the radicals R, independently of one another, are hydrogen or aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radicals, which may be bonded to one another to form a ring, and m is 0 or 1, are prepared by reacting an acetal or ketal of the formula II with an acetylene or allene of the formula III or IV where R and R1 have the abovementioned meanings, in the gas phase at elevated temperatures in the presence of a zinc- or cadmium- and silicon- and oxygen-containing heterogeneous catalyst.
