RR1C(CN)- NR2R3 (R = Me or Ph, R1 = H or Me, R2 and R3 = Et or R2R,3 = piperidino), treated with Na in refluxing MePh gave, in addn. to the corresponding RR1CHNR2R3, ethylenediamine derivs., [RR1C(NR2R3)]2, which were formed by the replacement of 1 CN group by the CN-free residue of another mol. alpha -Piperidinoisobutyronitrile, m. 43-5 Deg (0.75 mole), in 250 cc. MePh added slowly to 0.75 g.-atom powd. Na in hot MePh gave 42% N-isopropylpiperidine, b15 42 Deg, and 8% 2,3-dipiperidino-2,3-dimethylbutane, b0.4 110-13 Deg. alpha -Piperidinopropionitrile, b15 92-5 Deg, gave similarly 43% 1-ethylpiperidine, b20 40 Deg, and 22% 2,3-dipiperidinobutane, b15 148-9 Deg. PhCH(CN)NEt2, b13 134-5 Deg, yielded 39% PhCH2NEt2, b16 85-7 Deg, and 45% reddish yellow [PhCH(NEt2)]2, b0.4 140 Deg.
