    Description / Table of Contents: Zusammenfassung 1.3-Dihalogendisilazane wurden durch Umsetzung von Cyclo_und Polysilazanen mit Halogenwassertoffen (Rkk. 2,7) oder mit Dichlorsilanen (Rkk. 5, 9) erhalten und in den Verbin-dungen I–IX charakterisiert (Tab. 1). Thre vielseitigen Reaktionen lassen sich in Schema 1 überblicken.
    Notes: Abstract We obtained 1.3-dihalogenodisilazanes by reaction of cycloor polysilazanes with hydrogen halogenides (equ. 2, 7) or with dichlorosilanes (equ. 5, 9). They are characterized in the compounds I–IX (Table 1). A survey on their versatile reactions is given in scheme 1.

    Notes: Abstract Sila-analoguesA 2 andB 2 of two drugs from the benzhydryl ether class, chlorphenoxamine and clofenetamine, were synthesized for the first time by the steps shown in scheme 1. They and their precursors I–VI were characterized by their physical (Table 1) and chemical properties and their structures confirmed by n.m.r., mass and infrared spectrocopy (Tables 2–5). Their physiological effects were investigated and compared with those of the carbon analogues (Chapter 5).

    Notes: Abstract Sila-analoguesA 2,B 2 andC 2 of the drug mebrophenhydramine from the class of benzhydryl ethers were synthesized for the first time by the steps shown in scheme 1, and they and their precursors I–III were characterized by their physical (Table 1) and chemical properties, and their structures confirmed by NMR, mass and infrared spectroscopy (Tables 3–5). The histaminolytic and anticholinergic effects ofA 2 andC 2 were investigated and compared with some structure-activity relationships of analogue carbon compounds.

    Notes: Abstract Sila-AnaloguesB 2 andA 2 of the spasmolytic ciclonium bromide (B 1) respectively the corresponding free baseA 1 were synthesized for the first time according to the reaction steps shown in scheme 1, and they and their precursors I and II were characterized by physical (Table 1) and chemical properties and their structures confirmed by NMR, and mass spectroscopy (Tables 2 and 3). The pharmacological effects ofA 2 andB 2 were investigated and compared with those of the parent carbon compoundB 1 (chapter 5).

    Notes: Abstract DerivativesA andB of the two sila-antihistamines silamephenhydramine and sila-chlorphenoxamine were synthesized for the first time by the steps shown in scheme 1. They and their precursors III and IV were characterized by their physical (Table 1) and chemical properties and their structures confirmed by NMR and mass spectroscopy (Tables 2 and 3). Their pharmacological effects were investigated and compared with those of the corresponding sila-antihistamines.

    Notes: Abstract Isoelectronic derivatives (A andB) and a homolog (C) of the two sila-antihistamines sila-clofenetamine and sila-mebrophenhydramine were synthesized for the first time by the steps shown in scheme 1. They and their unknown precursors II–IV were characterized by their physical (Table 1) and chemical properties and their structures confirmed by1H-NMR and mass spectroscopy (Tables 2 and 3). The pharmacological effects ofA andB were investigated and compared with those of the corresponding O-isosteric sila-antihistamines (Chapter 5).

    Description / Table of Contents: Zusammenfassung Spezielle Umsetzungen von 1,3-Dichlordisilazanen werden beschrieben. Die Umsetzung mit einem bestimmten Amin führte zu einer SiNSiN-Verbindung mit 6 verschiedenen Substituenten (I; Rk. 1). Analog bildeten sich mit Hydrazinen Bis(hydrazino)-disilazane der Strukturgruppe NNSiNSiNN (II, III; Rk. 2). Mit Äthylendiamin konnte ein Si2N3C2-Siebenringsystem (IV), mit Bis(trimethylsilyl)harnstoff ein Sechsringsystem Si2N3C (VI), mit Diphenylsilandiol das Cyclotrisildioxazan-Sechsringsystem (VIII, IX) aufgebaut werden. 1,3-Dichlordisiloxan ergab in ähnlichen Umsetzungen erstmalig ein Si2N2OC2-Siebenringsystem (V) und ein Si2N2OC-Sechsringsystem (VII).
    Notes: Abstract Special reactions of 1.3-dichlorodisilazanes give a) with a special amine a SiNSiN-compound with 6 different substituents (I; equ. 1); b) with hydrazines bis(hydrazino)disilazanes of the structural unit NNSiNSiNN (II, III; equ. 2); c) with ethylenediamine a novel Si2N3C2-sevenmembered ring system (IV); d) with bis(trimethylsilyl)urea a sevenmembered ring system Si2N3C (VI); e) with diphenylsilanediol the cyclotrisildioxazane ring system (VIII, IX). Analogous reactions of 1.3-dichlorodisiloxanes lead to the novel sevenmembered ring system Si2N2OC2 (V) and to the sixmembered Si2N2OC-ring system (VII).
