    Description / Table of Contents: Complexes of Chromium, Molybdenum, and Tungsten with Aminoarsanes as LigandsThe aminoarsanes Me2As—NMe2, MeAs(NMe2)2, and As(NMe2)3 form with the carbonyles of the sub-group VI metals complexes of the general formula (CO)5M—L (L = aminoarsane; M = Cr, Mo, W). The cleavage of the As—N bond by reactions with acids HX results in the formation of complexes of the general formula (CO)5M—As(Me2)—X, (CO)5M—As(Me)X2, and (CO)5M—AsX3.
    Notes: Die Aminoarsane Me2As—NMe2, MeAs(NMe2)2 und As(NMe2)3 bilden mit den Carbonylen der Metalle der VI. Nebengruppe Komplexe der allgemeinen Formel (CO)5M—L (L = Aminoarsan; M = Cr, Mo, W). Die Spaltung der As—N-Bindung mit Säuren HX führt zur Bildung von Komplexen der Formel (CO)5M—As(Me2)—X, (CO)5M—As(Me)X2 und (CO)5M—AsX3.

IIThe reaction of the amino compounds MeyB—NMe2 (B = As, y = 2; B = Si, y = 3) with 1, n-dioles results in the formation of the compounds HO(CH2)nOBMey. These compounds can be used as the arms of pode-type molecules MexA[—O(CH2)nOBMey]z with A = Si, As. The influence of A, B, n, and z in the rearrangement of these molecules is examined.A second type of pode molecules can be prepared by the reaction of Me2As—R—OH (R = CH2CH2, CH2CH2(OCH2CH2)2) with the amino compounds Mex(NMe2)z (A = As, Si). These reactions result in the formation of molecules as MexA(ORAsMe2)z.

Der Einfluß von A, B, n und z auf die Umlagerung dieser Moleküle wird untersucht.Eine zweite Klasse „anorganischer„ Tintenfisch-Moleküle wird durch Umsetzung von Me2As—R—OH (R = CH2CH2, CH2CH2(OCH2CH2)2) mit den Amino-Verbindungen MexA(NMe2)z (A = As, Si) erhalten.
