    • 5 and 36 gL (0.3 mmol) of optically pure (R)-I-phenylethanol are added. This solution is stirred one hour before being introduced in the flask containing the rhodium complex. After 2 hours stirring, a solution of l.08 g (4.32 mmol) of a commercial mixture of di and triisocyanate (diphenylmethane diisocyanate, MERCK, Art. 820797; diisocyanates : 6556, triisocyanates : 30%) in l.5 mL of dichloromethane is added. The polyaddition is exothermic. The solution was stirred overnight at room temperature. The solvent is evaporated and the polymer is crushed and washed with 500 mL of 2-propanol during 24 hours. Finally, it is filtered through a Millipore filter (vv type, pore size 0.10µm) and dried.

    • −3 mmol of rhodium that is 5 mol%) is dried under vacuum during 3 hours. Then 2 mL of a l.3 10-2 mol.L-I potassium tert-butoxide solution in 2-propanol is added under an inert atmosphere of argon. 15µL (0.1 1 mmol) of substrate is introduced with a syringe. Conversion and enantiomeric excess are monitored by GC. The different experiments are performed 5 times.
