Abstract: In the process for the preparation of vinyloxime ethers of the formula Iby reacting an oxime with an alkynewhereR1 and R2 are identical or different and are alkyl or aryl radicals,R3 is hydrogen, an alkyl or aryl radical, andR4 is a radical having the meaning of R3, which may be different than R3, or is a hydroxyalkyl radical,in a superbasic polar organic solvent in the presence of a strong base, the reaction is carried out under conditions such that the resulting vinyloxime ether stays in contact with the other constituents of the reaction mixture for only a short time so that it is unable to decompose or react to give secondary products to a significant extent.

Abstract: Enol ethers (I) are produced by reacting alcohols (II) and/or acetals or ketals (III) derived from (I) with acetylenes (IV) and/or allenes (V), using a mol ratio of (II + III):(IV/V) = 1 or more and working up the product by distillation with recycling of acetal and alcohol, possibly after catalytic acetalization of excess alcohol with the enol ether. A process for the production of enol ethers of formula (I) by reaction of alcohols (II) and/or acetals or ketals (III) with acetylenes (IV) and/or allenes (V) in the gas-phase at elevated temperature in presence of a heterogeneous catalyst containing zinc or cadmium together with silicon and oxygen, followed by distillation to give (I): R = an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic residue (all optionally with other substituents which do not react with acetylenes or allenes); R = H or organic groups as listed for R , which may combine to form rings; m = 0 or 1. In this process, (a) the reaction is carried out with a mol ratio of (II + III):(IV and/or V) = 1 or more, in such a way that the product leaving the reactor (containing I with excess II and III) is practically free from acetylene or allene, after which (b1) this product is immediately distilled to give an azeotrope comprising (I) and (II) as the top fraction (possibly containing unreacted IV/V), enol ether (I) as intermediate fraction and (III) as bottom product, the top and bottom fractions being returned to the reactor, with the proviso that the reaction conditions and the mol ratio of the reactor feed are such that the mol ratio of (I) to (II) in the reactor product is greater than that in the azeotrope, or (b2) if (I) and (II) do not form an azeotrope, the reactor product is immediately distilled to give (I) as top product and a mixture of (III) and (II) as bottom product which is returned to the reactor, and/or (c) the product from the reactor is subjected to reaction at below 100 deg C on an acetalization catalyst, resulting in reaction of excess (II) with the product (I) to form acetal (III), followed by distillation to give the product (I) and acetal (III) which is returned to the reactor.
