Novel Hydroformylation catalysts

摘要: Abstract Cobalt carbonyl complexes containing a complementary tertiary phosphine, arsine or phosphite ligand, e.g., [Co(CO)3PBu3]2, have catalytic properties for the hydroformylation of olefins which are considerably different from those dicobalt octacarbonyl. These novel catalysts unusual because many active at low pressures (100–300 psi), produce alcohols rather than aldehydes as primary product and exhibit high preference reaction terminal carbon position I-olefins.
