Dimerization of acrylonitrile or acrylic acid esters catalyzed by tervalent phosphorus compounds has been studied in great detail, 1, 2) since the reaction furnishes industrially important products. 3) However, the study of the catalyzed reaction has been restricted only to dimerization. 4) In a previous paper, 5) we reported the reaction of acrylonitrile or acrylates with aldehydes to produce 2-(1-hydroxyalkyl) acrylonitriles or-acrylates in the ...
