    Description / Table of Contents: Diyne-Reaction, 42.  -  Complex-chemical Synthesis of Substituted 1,4-Naphthoquinones and Isoheterocondensed BenzoquinonesThe bis(acetyleneketones) 7a-c and 8a, d react with tris(triphenylphosphine)rhodium(I)-chloride to form complexes of different strukture, which further react with acetylene derivates to give the substituted 1,4-naphthoquinones 14-19, a-d, and with chalcogens or nitrosobenzene to give the isoheterocondensed benzoquinones 21-24, b-d. Thermal isomerisation of 7b and c yields the 1,4-anthraquinones 25b and c.
    Notes: Die Bis(acetylenketone) 7a-c und 8a, d geben mit Tris(triphenylphosphin)rhodium(I)-chlorid Komplexe unterschiedlicher Struktur, die mit Acetylenderivaten zu den substituierten 1,4 Naphthochinonen 14-19. a-d, mit Chalkogenen oder Nitrosobenzol zu den isoheterokondensierten Benzochinonen 21-24, b-d weiterreagieren. Bei der thermischen Isomerisierung von 7b und c entstehen die 1,4-Anthrachinone 25b. c.

    Notes: Hermann Staudinger, der Begründer der Polymerchemie, wäre 1981 hundert Jahre alt geworden. Eine der Schlüsselsubstanzen, an denen er den Aufbau der Hochpolymere aufklärte, war Polystyrol. - Polystyrol, einer der bedeutendsten thermoplastischen Kunststoffe, wird seit fünfzig Jahren industriell erzeugt. Es hat nicht nur unser tägliches Leben erleichtert, es war auch Modellsubstanz für den Auf- und Ausbau der Polymerchemie und -physik, es war Pioniermaterial für den verfahrenstechnischen Umgang mit Polymerlösungen und -schmelzen. Dieser Beitrag gibt eine Übersicht über die Entwicklung und den gegenwärtigen Stand der Kenntnisse über die Polymerisation des Styrols und über die Zusammenhänge zwischen Struktur und Eigenschaften.

    Notes: Hermann Staudinger, the founder of polymer chemistry, would have been 100 years old this year. One of the key materials with which he elucidated the structure of high polymers was polystyrene. - Polystyrene, one of the most important thermoplastics, has now been manufactured industrially for some 50 years. Not only has it simplified our daily lives in a variety of ways, it has also been a model substance for the development and expansion of polymer chemistry and polymer physics, and it was the pioneering material for handling polymer solutions and melts. This article surveys the development and present state of knowledge of the polymerization of styrene and of the relationships between structure and properties.
