In earlier hydroformylation studies modification of the Rh catalyst with o-methyl-substituted or o-ethyl-substituted phosphane ligands have increased regioselectivity to branched aldehydes. The promising results achieved created a need for further studies. Thus, a wider group of o-substituted arylphosphane ligands were synthesized and tested in Rh-catalyzed hydroformylation to support the previous findings. In the Rh-catalyzed hydroformylation of propylene and 1-hexene the ligands increased the formation of branched aldehydes compared to triphenylphosphane. The increasing size of the o-alkyl-substituent affected favorably iso-selectivity.
