Abstract
1. 1,2-Bis(p-tolylamino)ethane has been found to be a more satisfactory and specific reagent for the characterization of aldehydes than l,2-bis(benzylamino)ethane,1, 2-bis(p-methoxybenzylamino)ethane or l,2-bis(p-chlorobenzylamino)ethane. It has also been found that the reaction between the reagent and acetone, acetophenone and some aldoses and ketoses is not noticeable.2. A modified method for preparing 1,2-bis(p-tolylamino)ethane is recommended and three new derivatives of this compound were prepared; namely, N, N′-diacetyl-and N, N′-dibenzoyl-1,2-bis(p-tolvlamino)ethane, and N, N′-bis(p-tolyl)piperazine.3. Twenty-four aldehydes were tested with 1,2-bis(p-tolylamino)ethane, and the corresponding derivatives 2-substituted 1,3-di(p-tolyl)tetrahydroimidazoles were obtained.4. On treating with dilute hydrochloric acid, these derivatives could be decomposed into the correspounding aldehydes and the dihydrochloride salt of the reagent and some aldehydes could be recovered almost quantitatively.
