摘要：

The title protocol utilizes CF3C6F11 Solutions of ClRh[P(CH2CH2(CF2)(n-1)CF3)(3)](3) (n=6, 8; 0.8-0.2 mol%) and toluene (biphasic conditions, 60 degrees C) or hexanes or ether (monophasic conditions, 28-60 degrees C) solutions of PhMe2SiH and cyclic enones or ketones. Samples are cooled to room temperature or -30 degrees C, and simple organic/fluorous phase separations remove products from the catalyst, which can be directly reused without loss of activity.
