A series of [2.2]paracyclophane-derived frustrated Lewis pairs (FLPs) with reversible, metal-free hydrogen activation was synthesized and successfully applied in the hydrogenation of imines in moderate to good yields. The high stability of the novel FLP system enables effective recycling of the metal-free catalysts. This reaction could also be compatible with a larger scale and developed into a pharmaceutical synthesis of cinacalcet {(R)-N-[1-(1-naphthyl) ethyl]-3-[3-(trifluoromethyl)phenyl]propan-1-amine} without heavy metal residues.
