cf. CA 54, 21642d. Dimerizing redn. of N-benzylidenebutylamine with Al amalgam gave a mixt. of meso-(I)and dl-N,N'-dibutyl-alpha ,alpha '-diphen- ylethylenediamine (II) which were isolated by Craig distribution (Schoenenberger, CA 52, 18274h). The constellations of I and II were detd. by reaction with CH2O to form imidazolines and measurement of the rate of hydrolysis, by reaction with CS2 at ...
