Abstract
Phosphorus-containing calixarenes of the general formula I ##STR1## and a process for their preparation are described. Additionally, a process for the preparation of aldehydes by the hydroformylation of C.sub.3 -C.sub.20 -olefins by means of rhodium or ruthenium carbonyl complexes, in which the phosphorus-containing calixarenes of the formula I are used as ligands, is described.
