__d__,__l__‐1, 2‐Dianilino‐1,2‐diphenyl‐ethane reacts readily and specifically with aldehydes to form substituted __d__, __l__‐1,3,4,5‐tetraphenylimidazolidines, which are highly crystalline compounds with sharp melting points distributed over a wide range of temperature. The reaction has been used
## Abstract Formaldehyde and acetaldehyde react with either __d__, __l__‐ or __meso__‐1, 2‐dianilino‐1, 2‐diphenyl‐ethane (I) in acetic acid‐acetone solution at room temperature to give quantitatively the tetraphenylimidazolidines IV and V.
## Abstract Pure β‐dehydro‐elsholtzione is obtained by means of the sodium salt of its bisulfite compound. The __syn__ and __anti__ 2,4‐dinitrophenylhydrazones are prepared. The KISHNER‐WOLFF reduction of elsholtzione gives the corresponding furan, which by hydrogenation is converted into a mixture
