    Description / Table of Contents: Reaction of Arsolanes, Arsenanes, and Arsepines with OximesThe reaction of methyl-substituted arsolanes, arsenanes and arsepines with oximes results in it opening of the cyclic arsinous acid esters. In the course of the reaction of the substituted arsolanes (CH2)2O2As—X[X = N(CH3)2, OCH3, Cl] and (CH2)2ON(CH3)As—N(CH3)2 with oximes the group X is substituted by the oxime; an opening of the rings does not take place.
    Notes: Die Umsetzung methyl-substituierter Arsolane, Arsenane und Arsepine mit Oximen führt zu einer Ringöffnung der cyclischen Arsenigsäureester. Bei Umsetzung der substituierten Arsolane (CH2)2O2As—;X[X = N(CH3)2, OCH3, Cl] und (CH2)2ON(CH3)As—N(CH3)2 mit Oximen wird die Gruppe X durch das Oxim substituiert; eine Ringöffnung findet nicht statt.

    Description / Table of Contents: α ω-Alkane-bis-dimethylarsine Sulfides and Selenides, a Novel Class of LigandsThe reaction of α,ω-alkane-bis-dimethylarsanes (CH3)2As—(CH2)n—As (CH3)2 with sulfur and selenium results in formation of the sulfides and selenides, respectively, (CH3)2As(X)—(CH2)n—As(CH3)2 or (CH3)2As(X)—(CH2)n—As(X)(CH3)2 (X = S, Se), which form chelat-complexes with the salts CoX2 · 6 H2O (X = Cl-, Br-, I-, NO3-). The UV-spectra of the complexes are presented and discussed.

    Description / Table of Contents: Reaction of Dimethylarsinous Acid Glycolesters with HalidesThe reactions of dimethylarsinous acid glycolesters with the halides XE (X = F, CL; E = AsF2, AsCl2, Pcl2, COR, SiMe3, SiClMe2), with trimethylaluminium and diols have been investigated. All the reactions can be described by an universal mechanism as Lewis acid base reactions.The glass of the dimethylarsinous acid glycolesters is extended to the esters of the 1,n-diols (n = 3,4).
    Notes: Die Reaktionen der Arsenigsäureester Me2As—ORO—X (Me≡CH3; X = H, AsMe2) mit den Halogeniden XE (X = F, Cl; E = AsF2, AsCl2, Pcl2, COR, SiMe3, SiClMe2), mit Aluminiumtrimethyl und Diolen werden untersucht. Alle Umsetzungen lassen sich nach einem gemeinsamen Mechanismus als Lewis-Säure-Basen-Reaktionen beschreiben.Die Stoffklasse der Arsenigsäure-diolester wird auf die Ester der 1,n-Diole (n = 3,4) erweitert.

    Description / Table of Contents: Synthesis and Properties of Bis-[dialkylamino-methyl-arsino]-methanesThe reactions of methan-bis-[methyl-chlorarsine] H2C[As(CH3)Cl]2 with secondary amines lead to the formation of bis-[dialkylamino-methylarsino]methanes H2C[As(CH3)NR2]2. The cleavage of the As—N bond with acid molecules HX (X=OH, OR, SR, NR2, halogen) results in the formation of the compounds H2C[As(CH3)X]2. The IR and 1H-NMR spectra are discussed and presented.
