Abstract: The invention concerns a process for preparing aldehydes by the hydroformylation of olefins with CO/H2 in the presence of complexes of transition metals of subgroup VIII of the periodic system of elements, which complexes contain phosphorus compounds as ligands. The process is carried out at temperatures of up to 200 DEG C and pressures of up to 700 bar and uses catalysts which contain as ligands lambda , sigma -phosphorus compounds which can act as complexing agents. The invention further concerns novel phosphabenzenes.
