Isopropyl diarylphosphinites (Ar2POPri) catalyse the dimerisation of acrylonitrile (AN) to a mixture of cis-and trans-1, 4-dicyanobut-1-ene (cis, trans-DCB-1), trans-1, 4-dicyanobut-2- ene (DCB-2) and 2, 4-dicyanobut-1-ene (MGN). The kinetics and mechanism of the reaction, which is a potential source of hexamethylenediamine, are reported in detail and the factors which govern rate and selectivity to DCB-1 and DCB-2 rather than MGN are elaborated.
