## 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.

SUMMARY
Four 2,4-disubstituted 6,7-dihydro-imidazo[l, 2-a]-s-triazincs (IV, VII, X and XV) have been synthesized according to the following scheme : (a) monosubstitution of cyanuric chloride (I) with ethanolaminc, (b) replacement of the remaining chlorine atoms by suitable groups, and (c) cyclisntion of the 2'-hydroxy-ethylamino side chain on one of the adjacent cyclic nitrogen atoms of the s-triazine nucleus. This last step includes reaction of the 2-[(a-hydroxy-ethyl)-amino]-s-triazines with thionyl chloride or p-toluenesulfonyl chloride and, with one exception (VIII +-IX), heating the resulting 2-[(2-chloro-ethyl)-amino] derivatives or p-toluenesulfonic esters in a solvent.

## Abstract Dimethylformamide has been found to give solid complexes with both d,l and meso 1,2‐dianilino‐1, 2‐diphenylethanes (I), but only with the meso forms of 1,2‐di‐o‐ and 1,2‐di‐p‐toluidino‐1,2‐diphenylethanes (resp. II and III). These complexes are particularly suitable for the separation o
