Abstract
The present invention relates to a process for the hydroformylation of terminal and internal olefins in a two-phase system using novel metal catalysts. The two-phase system consists of an aqueous and an organic phase. The metals belong to group VIII of the Periodic Table, e.g., Rh, Ru, Ir, Co or Pd. The ligands for the metals are novel phosphane-modified .beta.-cyclodextrins which are water-soluble.
Claims4
A .beta.-cyclodextrin modified diphosphine comprising a bis (diarylphosphinomethyl) amino or bis (dialkylphosphinomethyl) amino moiety bonded indirectly through a spacer or directly to the 6-position of .beta.-cyclodextrin or an alkylated form of .beta.-cyclodextrin.
