Abstract
Addition of hydroxylamine, ammonia and hydrocyanic acid to 4-benzoylamino-3-keto-2-(δ-carbomethoxybutylidene)-thiophane and to 4-benzoylamino-3-keto-2-benzylidenethiophane has been investigated. 4-Benzoylamino-3-keto-2-(δ-carbomethoxybutylidene) thiophane participates in a nucleophilic addition reaction both at the carbonyl group, and at the multiple bond, unlike 4-benzoylamino-3-keto-2-benzylidene-thiophane, which reacts only at the carbonyl group.
