Ligands behaving badly: A series of hindered biaryl phosphine compounds are used as ligands in rhodium‐ catalyzed hydroformylation. In situ analysis of the resultant catalysts under operating conditions shows that the ligands are dissociated under high pressures of syngas, thereby creating an unselective rhodium catalyst for the hydroformylation.
