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,
