Reaction Steps

In a glove box, tBu2PH(C6F4)BH(C6F5)2 (0.33 g, 0.05 mmol) and cis-1,2,3-triphenylaziridine (0.271 g, 1.0 mmol) were weighed into a 100 ml round bottomed glass flask equipped with a Kontes valve and a magnetic stirbar. Toluene (4 ml) is added, the reaction transferred to a vacuum/H2 line and the mixture is freeze-pump-thaw cycled three times. The mixture is cooled to −196° C. (liquid N2) and 1 atm. H2 is introduced. The flask is sealed, the reaction is placed in a 120° C. preheated bath and rapidly (500 rpm) stirred. The reaction is periodically monitored by 1H NMR spectroscopy and is complete in 2 hours. The reaction mixture is poured onto a small plug of silica and eluted with 2:1 hexanes/ethyl acetate (50 ml). The solvent is removed in vacuo and the product N-1,2-diphenylethyl-N-phenyl amine isolated. Yield: 0.269 g (98%)
