    Description / Table of Contents: Dimethyldithiocarbamatoarsanes and -stibanesThe Halogeno-bis(dimethyldithiocarbamato)-compounds (dtc)2AsCl 1, (dtc)2AsBr 2, (dtc)2AsI 3 and (dtc)2SbI 4 are prepared from (dtc)3As and (dtc)3Sb resp. Reaction of 1 to 4 with CF3SO3Sime3 yields the ionic compounds (dtc)2As+CF3SO3- 5 and [(dtc)2El+]2Hal-(CF3SO3-) · CH2Cl2 6 (El = As; Hal = I), 7 (El = Sb; Hal = I) and 8 (El = As; Hal = Br) resp. by elimination of me3SiHal. The mass spectra and the main fragmentation from 1 to 8 are reported. The vibrational spectra of these compounds, of As(dtc)3, Sb(dtc)3 and of the antimony compounds which are corresponding to 6 and 8 are discussed.
    Notes: Die Synthese der Halogeno-bis(dimethyldi-thiocarbamato)-Verbindungen (dtc)2AsCl 1, (dtc)2AsBr 2, (dtc)2AsI 3 und (dtc)2SbI 4 aus (dtc)3As bzw. (dtc)3Sb wird beschrieben. Umsetzungen von 1 bis 4 mit CF3SO3Sime3 führen unter me3SiHal-Abspaltung zu den salzartigen Verbindungen (dtc)2As1CF3SO3 5 bzw. [(dtc)2El1]2Hal (CF3SO3) · CH2Cl2 6 (El = As; Hal = I), 7 (El = Sb; Hal = I) und 8 (El = As; Hal = Br). Die Massenspektren und die Hauptzerfallswege von 1 bis 8 werden mitgeteilt. Die Schwingungsspektren von 1 bis 8, As(dtc)3, Sb(dtc)3 sowie den 6 und 8 entsprechenden Antimonverbindungen werden diskutiert.
