摘要:A method of preparing an α-cyanoacrylate ester of a desired alcohol includes the steps of n preparing a compound which is an α-selenoaryl-α-cyanopropionate ester of the desired alcohol, n oxidizing said α-selenoaryl-α-cyanopropionate ester to the corresponding selenoxide, n eliminating arylselenic acid from the selenoxide to produce said α-cyanoacrylate ester, and n separating said α-cyanoacrylate ester from the selenic acid. n At temperatures of about 0° C. or higher, the elimination step occurs concurrently with the oxidizing step using a peroxide or ozone oxidizing agent. The desired cyanoacrylate ester is obtained in good yield and very high purity. The method can be used to prepare difficult to synthesize plural functional cyanoacrylate monomers and mono- cyanoacrylate monomers regardless of alcohol chain length.

摘要:The high temperatures required for cracking the cyanoacrylate oligomers, produced by the Knovenagel condensation of formaldehyde and a cyanoacetate, limit the synthetic diversity and the number of different side chains that can be incorporated into a cyanoacrylate prepared using this method. Accordingly, the diversity of cyanoacrylate monomers prepared industrially is quite limited. Disclosed herein is a method for the preparation of alpha-Cyanoacrylate ester monomers from a variety of phosphonium and ammonium alpha-cyanoacrylate salts. The phosphonium and ammonium alpha-cyanoacrylate salts are of the general formula:
