ETA 5-PHOSPHOLYL COMPLEXES AND ETA 5-POLYPHOSPHOLYL COMPLEXES AND THEIR USE IN HYDROFORMYLATION

摘要

The invention relates to a method for producing aldehydes by hydroformylating olefins with CO/H2 in the presence of complexes of transition metals of subgroup VIII of the periodic table of elements at temperatures ranging from 20 to 200 °C and with atmospheric pressures of up to 700 bar. According to the inventive method, catalysts comprising θ5-phospholyl complexes or θ5-polyphospholyl complexes which are capable of forming complexes are used as ligands.
