By a sol–gel process a rhodium complex containing a diphosphane with a large natural P‐Rh‐P bite angle is covalently anchored in a silica matrix (see picture). The immobilized catalyst is a very selective hydroformylation catalyst that is completely and conveniently separated from the product and can be reused in numerous cycles.
