Typical procedure: Cyclodextrin diphosphane (2.4 × 10−5mol) and [Rh(cod)2]BF4(2 × 10−5mol) were dissolved in DMF (5 mL). H2O (15 mL) and 1‐octene (10 mL) were added and the hydroformylation was carried out in a steel autoclave (200 mL) equipped with a teflon sleeve and a magnetic stirrer at a temperature of 60 °C under a synthesis gas atmosphere (CO/H21/1; 100 bar). After completion of the reaction (Table 1) the mixture was poured into a separating funnel the aqueous catalyst solution removed and washed with H2O (10 mL) to remove residual DMF. The organic phase was then dried over MgSO4and filtered.
