Straight-chain acrylonitrile dimers including 1,4-dicyanobutene, 1,4-dicyanobutadiene and adiponitrile are produced at a high selectivity rate and yield by dimerizing acrylonitrile in the presence of a catalyst comprising at least one ruthenium compound, for example dichloro-tetrakis (dimethylsulfoxide) ruthenium, and in the presence of at least one organic acid, for example, propionic acid, and optionally in the further presence of a basic compound, a reducing compound and/or a sulfoxide compound.
