Thies, Heinrich ; Schönenberger, Helmut ; Qasba, P. K.


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 ...
