New N,S-Substituted Nitrobutadienes from Mono(Arylthio)Substituted Nitrobutadienes

N,S-Substituted nitrobutadienes 3a-g were synthesized from the reaction of the thiosubstituted derivatives 1a-g with thiomorpholine 2. The N,S-substituted nitrobutadienes 5a-g were obtained from the reaction of the thiosubstituted butadienes 1a-g with N-diphenylmethyl piperazine 4. The structure of butadiene 3c was elucidated by single crystal X-ray diffraction
