Article abstract of DOI:10.1007/BF00817601

β-Chloro-α-cyano-cinnamonitrile(1) reacts in one step with α-oxo-thioles 3 or successively with sodium sulphide and α-chlorocarbonyl compounds 4 to form the 5-substituted 4-amino-2-phenyl-thiophene-3-carbonitriles 5.Analogously, the successive reactions o
