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.
