✦ Synopsis
In continuation of our inveatigatione into the reactivity of S-alkyl derivatives of thiohydantoins against nucleophylea, cf. eg.l, an attempt has been made to bring these S-alkyl derivativea, eg. 2,!Fbis/methylthio/-4, 'hdiphenyl-*H-imidaxole /I/ into reaction with different/potential/ carbanions, eg. ethyl malonate, acetylacetone, *odium cyanide etc.; all our attempts to realise this air, however, failed.
