    Description / Table of Contents: The preparations of certain amino dialkyl arsines (R2As—N(C2H5)2 and R2As—NC5H10 with R = C2H5, C3H7 or C4H9) are discribed. These compounds react with H2O, CH3J or HCl by cleaving the As—N bond, forming R2AsCl in the last case. The dialkyl chloro arsines are reduced by LiAlH4 to the corresponding arsines.
    Notes: Diäthylamino- und Piperidino-dichlorarsine reagieren mit aliphatischen Grignard-Verbindungen im Molverhältnis 1:2 unter Bildung der Amino-dialkylarsine R2As—N(C2H5)2 und R2As—NC5H10 (R = C2H5, C2H5, C3H7 oder C4H9). Die Amino-dialkylarsine sind äußerst hydrolyseempfindlich, wobei eine quantitative Spaltung der As—N-Bindung stattfindet. Eine Spaltung dieser Bindung resultiert gleichfalls mit HCl-Gas. Es werden hierbei Amin-hydrochloride und aliphatische Chlorarsine R2AsCl gebildet. Letztere lassen sich mit LiAlH4 zu den entsprechenden Dialkylarsinen R2AsH reduzieren. In den Amino-dialkylarsinen fungiert das Stickstoffatom als basisches Zentrum, wie aus der Ammoniumsalzbildung mittels CH3J zu folgern ist.

    Description / Table of Contents: Tertiary aromaric and aliphatic-aromatic arsines react with potassium in dioxan solution by decomposition forming the alkali arsides KAsR2 (R = C10H7-, p-CH3—C6H4—) and KAsRR′ (R = C6H5-; R = C2H5-, C6H11-). Cleaving only occurs with arsines containing two aromatic groups, but dialkyl-aryl arsines and trialkyl arsines are indifferent. Hydrolysis of KAsR2 and KAsRR′ yields the corresponding see, arsines and reaction with hydrocarbon halides gives the corresponding tert. arsines.
    Notes: Tertiäre aromatische sowie aliphatisch-aromatische Arsine reagieren mit Kalium in Dioxan unter Abspaltung eines Restes und Bildung der Alkali-arside des Typs KAsR2 (R = C10H7- und p-CH3—C6H4-) bzw. KAsRR′ (R = C6H5; R′ = C2H5; R′ = C2H5-, und C6H11-). Für eine positive Spaltung ist die Anwesenheit zweier aromatischer Reste Voraussetzung. Dialkyl-arylarsine und Trialkyl-arsine verhalten sich gegenüber Kalium in Dioxan indifferent. Nach Hydrolyse der Alkali-arside lassen sich die betreffenden sekundären Arsine gewinnen. Mit Alkylhalogenid liefern die Alkaliarside die entsprechenden tertiären Arsine.
