CATALYST COMPRISING A COMPLEX OF A METAL OF THE VIII. SUB-GROUP BASED ON A LIGAND WITH AN UNBRIDGED HETEROPHOSPHACYCLOHEXANE STRUCTURAL ELEMENT

摘要

The invention relates to a catalyst, comprising at least one complex of a platinate metal of the VIII. sub-group with at least one ligand with at least one unbridged heterophosphacyclohexane structural element, whereby the ligand is selected from heterophosphacyclohexanes of general formula (I), where A1, A2, A3 independently = O, S, SO2, NRa, SiRbRc or CRdRe with the proviso that at least one of the groups A1, A2, or A3 is not CRdRe, with the further proviso that at least one of the groups R2 to R5 is not hydrogen, a method for hydroformylation in the presence of such a catalyst and the use thereof, amongst other things for hydroformylation. The invention further relates to a method for hydrocyanation in the presence of a catalyst comprising a complex of such a ligand with nickel.
