Extremely high regioselectivities were achieved in the rhodium-catalyzed low-pressure hydroformylation of 1-octene to n-nonanal with chelate bisphosphites that contain a p-tert-butylcalix[4]arene backbone (shown in the picture). It was possible to tailor the structures and ultimately the catalytic properties of these complexes using molecular modeling calculations.
