Catalytic activity of bimetallic system composed with Rh(acac)(CO)₂ and cp₂Zr(CH₂PPh₂)₂ or cp₂ZrH(CH₂PPh₂) (cp = C₅H₅) in hex-1-ene, 1,5-hexadiene and 1,7-octadiene hydroformylation have been studied at 80°C, 10 atm of H2CO=1. Hydroformylation of hex-1-ene produces normal and branched aldehydes of 69–85% yield and n/iso ratio 1.8–2.0. Hydroformylation of dienes gives unsaturated monoaldehydes (ca. 30% yield). Applying ¹H, ³¹P NMR, UV-VIS and IR spectroscopy the following complexes have been identified: Rh(acac)(CO)₂L (1), Rh(acac)(CO)(L) (2), and Rh₄(CO)_xL_{12 − x} (3) (where: L = cp₂Zr(CH₂PPh₂)₂, cp₂ZrH(CH₂PPh₂), x = 8 – 11).
