Ethylenically unsaturated compounds are hydroformylated in the presence of a hydroformylation catalyst comprising at least one complex of a metal of transition group VIII with at least one phosphorus-containing compound as ligand, where this compound contains two groups which contain P atoms and are bound to a molecular skeleton derived from bisphenol A.

Os compostos ethylenically unsaturated são hydroformylated na presença de um catalizador do hydroformylation que compreende ao menos um complexo de um metal do grupo da transição VIII com ao menos o um composto phosphorus-containing como o ligand, onde este composto contem dois grupos que contêm átomos de P e é limitado a um esqueleto molecular derivado do bisphenol A.
