    Description / Table of Contents: 2,3-Di(1-naphthyl)butadien-1,3 und 2,3-Di(2-naphthyl)butadiene-1,3 wurden durch Dehydrobromierung von 2,3-Di(1-naphthyl)1,4-dibrombutan bzw. 2,3-Di(2-naphthyl)1,4-dibrombutan unter Verwendung von Natriumethoxid in Dimethylsulfoxid als Dehydrobromierungsmittel synthetisiert. Die 2,3-disubstituierten 1,3-Diene wurden mit Ausbeuten von 70 bis 80% erhalten und charakterisiert. Die Polymerisation der beiden Diene mit Azobisisobutyronitril ergab Poly[2,3-di(1(bzw. 2)-naphthyl)butadien-1,3]. Die Polymere wurden charaktersiert.
    Notes: 2,3-Di(1-naphthyl)butadicne-1,3 and 2,3-di(2-naphthyl)butadiene-1,3 were synthesized by dehydrobromination of 2,3-di(1-naphthyl)1,4-dibromobutane and 2,3-di(2-naphthyl)1,4-dibromobutane, respectively, using sodium ethoxide in dimethyl sulfoxide as the dehydrobrominating agent. The 2,3-disubstituted dienes-1,3 were obtained in yields of 70 to 80% and were characterized. Polymerization of either of the two dienes with azobisisobutyronitrile gave poly[2,3-di(1(or 2)-naphthyl)butadiene-1,3]. The polymers were characterized.
