    Abstract: The invention relates to a method for producing vinyl phosphonic acid compounds of general formula (I) wherein R and R are independently H, C1-16-aryl, C7-12-alkaryl or C7-12-aralkyl radicals, wherein the organic radicals can be substituted by one or several halogen atoms, hydroxyl, acyl or acetoxy groups. Production occurs by reacting phosphoric acid compounds of general formula (II) with acetylene in the presence of a Pd(II) complex and/or a Pd(0) complex or corresponding Pt complexes as a catalyst.

    Abstract: Novel oxime ethers of formula (I) are claimed as are also (i) prepn. of (I) by reaction of an oxime ether alcohol of formula (II) with an alkyne of formula (III) in presence of a base; and (ii) use of (i) as a comonomer in the prodn. of polymeric coatings or adhesives. R and R = H, 1-20C alkyl, 4-10C cycloalkyl, or 6-10C aryl or together form a 3-14C bridge; R = H, 1-4C alkyl or phenyl opt. with an inert substit.; n = 1-100; and A = 2-10C alkylene opt. with an inert substit.
