N,N′-Dibenzylethylenediammonium dichloride [PDF]
Acta Crystallographica Section E: Crystallographic CommunicationsThe isolation and crystalline structure of N,N′-dibenzylethylenediammonium dichloride, C16H22N22+·2Cl−, is reported. This was obtained as an unintended product of an attempted Curtius rearrangement that involved benzylamine as one of the reagents and 1,2-

The Curtius rearrangement. One step or two?
, 2012 The Curtius reaction is represented in most chemistry texts and notes as following path (a) below. It is one of a general class of thermally induced rearrangement which might be described as elimination/migration (in a sense similar to this ring contraction migration/elimination), in this case implicating a nitrene intermediate if the two steps occur ...
