    Description / Table of Contents: 1.3-Dipolar Cycloadditions, 64. Further Reactions of Nitrile Ylides with Hetero-multiple BondsThe products from cycloaddition of benzonitrile 4-nitrobenzylide (2) to the CN triple bond (ethyl cyanoformate, aryl cyanate), the CN double bond (benzylidenemethylamine) and the CS double bond (methyl dithiobenzoate and thionbenzoate, trithiocarbonic and thioncarbonicester) were structurally elucidated. The addition to nitrosobenzene is followed by a cycloreversion to give nitrone - nitrile. Nitrile ylides, nitrile imines and diazoalkanes are compared in their directions of cycloaddition.
    Notes: Die Cycloaddukte des Benzonitril-[4-nitro-benzylids] (2) an die CN-Dreifachbindung (Cyanameisensäureester, Aryl-cyanat), die CN-Doppelbindung (N-Benzyliden-methylamin) und die CS-Doppelbindung (Dithiobenzoesäureester, Thionbenzoesäureester, Trithiokohlensäureester, Thionkohlensäureester) werden strukturell gesichert. Der Anlagerung an Nitrosobenzol folgt eine Cycloreversion zu Nitron - Nitril. Die bei den Nitril-ylid-Cycloadditionen beobachteten Orientierungen werden mit denen des Diphenylnitrilimins und der Diazoalkane verglichen.
