    Description / Table of Contents: 2,4,4-Trichloro-1,2-dianisyl-cyclobutenylium Pentachlorostannate, a Crystalline Cyclobutenylium CationThe reaction of perchlorocyclobutenone with anisole under Friedel-Crafts conditions gives 2,4,4-trichloro-1,2-di-p-anisyl-1-cyclobutene (3). The crystalline cyclobutenylium cation 5 is synthesized by the reaction of 3 with hydrochloric acid and tin tetrachloride.

    Synthesen von PyrethroidsäurenProfessor Herbert Grünewald zum 60. Geburtstag gewidmet (1981)

    Notes: Im letzten Jahrzehnt wurde die Chemie der Insektizide durch neue Cyclopropancarbonsäureester spezifischer Struktur erweitert, die in ihrer Wirkung die bis dahin bekannten Insektizide aus anderen Stoffklassen und auch die natürlichen Vorbilder aus der Gruppe der Pyrethrum-Inhaltsstoffe bei weitem übertreffen. Diese Entdeckung hat eine Fülle vielfältiger synthetischer Arbeiten ausgelöst. Um selektive Synthesemethoden für komplizierte Kleinringe zu entwickeln, wurde ein umfangreiches Repertoire des synthetisch arbeitenden Chemikers aktiviert: So nutzt eine großtechnisch ausgeübte Synthese dieser Verbindungen sigmatrope Umlagerung, radikalische Addition und nucleophilen Ringschluß mit Carbanionen. Besondere Aktualität gewinnen diese neuen industriellen Synthesen durch die Anwendung stereospezifischer und enantioselektiver Methoden.

    Notes: In the course of the last decade the chemistry of insecticides was expanded with the discovery of new cyclopropanecarboxylic acid esters of specific structure, far superior in action to the hitherto known insecticides of other substance classes or the natural prototypes from the group of pyrethrum constituents. The discovery quickly precipitated a host of wide-ranging studies on the synthesis of these compounds. The development of selective methods of synthesizing complicated small rings called for a comprehensive repertoire: thus, synthesis of the compounds on an industrial scale makes use of sigmatropic rearrangement, radical addition, and nucleophilic ring closure with carbanions. These new industrial syntheses have acquired particular topicality because of their use of stereospecific and enantioselective methods.
