    Description / Table of Contents: Hydrolysis of 1-chloro-arsolane, C4H8AsCl, and 1-chloro-arsenane, C5H10AsCl, leads to oxides C8H10As2O and C10H20As2O, respectively. On direct alkylation of arsenic trioxide with 1.4-butane- and 1.5-pentane-bis-magnesium bromide these oxides are formed only in trifling amounts. Better results are gained by alkylation of N,N-dimethylaminodichloroarsane into amino-arsolane and amino-arsenane, which are also transformed into these oxides by hydrolysis. By hydrolysis of 1.4-dichloro-diarsenane only a small amount of 1.4-epoxo-arsenane is formed, whereas mainly a dimer of this oxide results. Solvolysis of 2.6-dichloro-diarsa-[3.3.0]-bicyclooctane with water, hydrogen sulphide or methylamine leads to 7-oxa-, 7-thia- and 7-methylaza-2.5-diarsa-noradamantane, respectively.
    Notes: Hydrolyse von 1-Chlor-arsolan, C4H8AsCl, und 1-Chlorarsenan, C5H10AsCl, führt zu Oxiden der Zusammensetzung C8H16As2O bzw. C10H20As2O. Die direkte Alkylierung von Arsentrioxid mit 1.4-Butan- und 1.5-Pentan-bis-magnesiumbromid liefert diese Oxide nur in geringen Ausbeuten. Günstiger verläuft die Alkylierung von N,N-Dimethylamino-dichlor-arsan zum Aminoarsolan und Amino-arsenan, die durch Hydrolyse ebenfalls in die Oxide überführt werden. Bei Hydrolyse von 1.4-Dichlor-diarsenan bildet sich wenig 1.4-Epoxo-arsenan, während in der Hauptsache ein Dimeres dieses Oxids entsteht. Solvolyse von 2.6-Dichlor-diarsa-[3.3.0]-bicyclooctan mit Wasser, Schwefelwasserstoff oder Methylamin führt zu 7-Oxa-, 7-Thia- und 7-Methylaza-2.5-diarsa-noradamantan.
