Abstract:
1. A process for the synthesis of a saturated long-chain α,ω-amino ester (acid) comprising from 6 to 17 carbon atoms, comprising, first, a cross metathesis reaction between a first acrylic compound, that is acrylonitrile, acrylic acid or an acrylic ester, and a second monounsaturated compound comprising at least one nitrile, acid or ester trivalent functional group, one of these compounds comprising a nitrile functional group and the other an acid or ester functional group, in the presence of a ruthenium carbenes metathesis catalyst, and, second, hydrogenation of monounsaturated nitrile-ester (acid) obtained in the presence of the metathesis catalyst from the cross metathesis reaction acting as hydrogenation catalyst.
