    Description / Table of Contents: Preparation of Dithiatetrazocine and Secondary ReactionsLi[PhCN2(SiMe3)2] (1) or PhCN2(SiMe3)3 (3) react with SCl2 to give in good yields the dithiatetrazocine PhC(NSN)2CPh (2). By analogy, p-MeC6H4C(NSN)2CC6H4Me-p (7), p-NO2C6H4C(NSN)2-CC6H4NO2-p (8), and p-CF3C6H4C(NSN)2CC6H4CF3-p (9) are obtained from the reaction of p-MeC6H4CN2(SiMe3)3 (4), Li[p-NO2-C6H4CN2(SiMe3)2] (5), und Li[p-CF3C6H4CN2(SiMe3)2] (6) with SCl2. Reaction of 2/LiCl with AgAsF6 in liquid SO2 leads to [PhCN2S2]+[AsF6]- (10) and 3[PhCN2S2]+2[AsF6]-Cl- (11). The structures of 10 and 11 are confirmed by X-ray analyses.
    Notes: Aus Li[PhCN2(SiMe3)2] (1) oder PhCN2(SiMe3)3 (3) und SCl2 wird das Dithiatetrazocin PhC(NSN)2CPh (2) in guter Ausbeute erhalten. Entsprechend gewinnt man aus p-MeC6H4CN2(SiMe3)3 (4), Li[p-NO2C6H4CN2(SiMe3)2] (5) und Li[p-NO2C6H4CN2(SiMe3)2] (6) mit SCl2 die Verbindungen p-MeC6H4C(NSN)2CC6H4Me-p (7), p-NO2C6H4C(NSN)2CC6H4NO2-p (8) und p-CF3C6H4C(NSN)2-CC6H4CF3-p (9). Die Reaktion von 2/LiCl mit AgAsF6 in flüssigem SO2 ergibt [PhCN2S2]+[AsF6]- (10) und 3[PhCN2-S2]+2[AsF6]-Cl- (11). Die Einkristallstrukturen von 10 und 11 werden mitgeteilt.
