ABSTRACT:
A catalyst comprising at least one complex of a metal of transition group VIII comprising at least one monodentate, bidentate or multidentate phosphinamidite ligand in which the phosphorus atom and the oxygen atom of the phosphinamidite group form part of a 5- to 8-membered heterocycle can be used for the hydroformylation and hydrocyanation of compounds containing at least one ethylenically unsaturated double bond. The phosphinamidite ligand is, for example, represented by the following formulaewhereinrepresents an optionally substituted 5- to 8-membered heterocycle wherein A represents carbon ring members;represents an optionally substituted N-bonded heterocycle wherein (Het) indicates optional ring heteroatoms in addition to the N; andB is a carbon-carbon single bond or a divalent bridging group.
