| titleOfInvention | Method of preparing β-alkoxyacrlonitriles |
| abstract | A process for the preparation of a beta -alkoxyacrylonitrile of the formula R'O-CH=CR-CN (C) where R is hydrogen or an alkyl moiety, among others, by contacting a compound of the formula (1/ alpha Me) O-CH=CR-CN (A) where Me is an alkali metal or alkaline earth metal and alpha is 1 or 2 respectively, an elevated temperature with a halogen compound of the formula R'Hal (B) where R' is among others a straight or branched alkyl or alkenyl moiety and Hal represents chlorine, bromine, or iodine. Also disclosed is a process for preparing a 3-amino-acrylonitrile of the formula <IMAGE> (D) where R5 and R6 represent, among others, hydrogen, alkyl or alkenyl by contacting a 3-alkoxyacrylonitrile or a metal salt of 3-hydroxyacrylonitrile with ammonia and/or amine. Also disclosed is a process for the preparation of such 3-aminoacrylonitrile by contacting a 3-alkoxyacrylonitrile of the formula <IMAGE> (C) where R' has the meaning given above and R7 has the same meaning as R stated above with an amine of the formula <IMAGE> (F) wherein R5 and R6 represent among others hydrogen, alkyl or alkenyl. The application further discloses a process for preparing a 3-amino-acrylonitrile of the formula <IMAGE> (D) where R5, R6 and R7 have the above meanings by contacting a compound of the formula <IMAGE> (A') with an amine. The Application also discloses the preparation of two-cyanovinyl esters by reaction of a cyanovinyl compound of the formula <IMAGE> (A'') with an acid halide or an acid anhydride. |
