    Description / Table of Contents: On the Ammonolysis of OrganylarsoranesReaction of pentaphenylarsorane and iminotribenzylarsorane with potassium amide in liquid ammonia gives, via a series of intermediates, the aza-analogue of arsenic acid, isolated as potassium salt (4). The nucleophilic attack of amide ions on organylarsoranes takes place at lower temperatures than in the case of analogue phosphorus compounds. For the ammonolysis of iminotribenzylarsorane a reaction mechanism different from that of the corresponding phosphorane is deduced.
    Notes: Die Reaktion von Pentaphenylarsoran und Iminotribenzylarsoran mit Kaliumamid in flüssigem Ammoniak führt über verschiedene Zwischenstufen zum Aza-Analogen der Arsensäure in Form eines Kaliumsalzes (4). Der nucleophile Angriff der Amid-Ionen auf Organylarsorane erfolgt bei niedrigeren Temperaturen als im Fall der analogen Phosphorverbindungen. Für die Ammonolyse des Iminotribenzylarsorans wird ein von der Reaktion des entsprechenden Phosphorans verschiedener Mechanismus abgeleitet.
