“…(Scheme 3, D ) [10]. As iron complexes are concerned, [FeCp(CO) 2 (PPh 2 NHNMe 2 ] + bearing a hydrazinophosphine ligand, which is closely related to PR 2 NHR’ ligands, was shown to react with n BuLi to give the carboxamido-phospha-ferracycle [FeCp(CO)( κ 2 ( C , P )-(CO)-NNMe 2 -PPh 2 )] (Scheme 3, E ) [11].…”

Treatment of [FeCp(CO)2Cl] with 1 equiv of the amidophosphine ligands Li[R2PNR′] (R = Ph, iPr, R′ = iPr, tBu, Cy) afforded complexes of the type [FeCp(CO)(κ2(C,P)-(CO)–NiPr-PPh2)] (1a), [FeCp(CO)(κ2(C,P)-(CO)-NtBu-PPh2)] (1b), and [FeCp(CO)(κ2(C,P)-(CO)-NCy-PiPr2)] (1c) in 40–50% yields. Complex 1a was also formed when [FeCp(CO)2(PPh2NHiPr)]+ (2) was reacted with 1 equiv of KOtBu. These complexes feature a four-membered carboxamido-phospha-ferracycle as a result of an intramolecular nucleophilic attack of the amidophosphine ligand on coordinated CO. Upon treatment of 1a with the electrophile [Me3O]BF4 the aminocarbene complex [FeCp(CO)(κ2(C,P)C(OMe)-NiPr-PPh2)]+ (3) was obtained bearing an aza-phospha-carbene moiety. Upon treatment of cis,trans,cis-[Fe(CO)2(Ph2PNHiPr)2(Br)2] (4a) and cis,trans,cis-[Fe(CO)2(Ph2PNHtBu)2(Br)2] (4b) with KOtBu the carboxamido-phospha-ferracycles trans-[Fe(CO)2(κ2(C,P)-(CO)-NiPr-PPh2)(Ph2PNHiPr)Br] (5a) and trans-[Fe(CO)2(κ2(C,P)-(CO)-NtBu-PPh2)(Ph2PNHtBu)Br] (5b) were formed in moderate yield. Finally, representative structures were determined by X-ray crystallography.

Das Salz K,SN, (1) reagiert in Acetonitril-Suspension bei -40°C mit Diorganylelementhalogeniden R,EX (E = P, As, Sb, Bi; X = CI oder Br) zu neuen Schwefeldiimiden S(N -ER,),. In der Reihe der terr-Butylverbindungen S(N-EtBu& (E = P (2b). As (3b), Sb (4b) und Bi (5b)) ist 3 b am bestindigsten; 5 b zersetzt sich unter Normalbedingungen. Weiterhin wurden die Arsenderivate S(N -AsR2)2 mit R = Methyl (3a), Cyclohexyl (3c) und Phenyl (3d) dargestellt. Die 1R-, NMR-und Massenspektren werden diskutiert. Sulfur Diimides Containing Organoelement Substituents of Main Group 5A suspension of the salt K2SN2 (1) in acetonitrile reacts with diorgano-element halides R,EX (E = P, As, Sb, Bi; X = CI or Br) at -40°C to give new sulfur diimides, S(N-ER,),. The arsino derivative 3 b is the most stable member of the series of tert-butyl compounds, S(N-EtBu& (E = P (2b), As (3b), Sb (4b). and Bi (Sb)), while 5 b decomposes under ambient conditions. The arsino derivatives S(N-AsR2), with R = methyl (3a), cyclohexyl (3c), and phenyl(3d) have also been prepared. The IR-, NMR-, and mass spectra are discussed.Substituierte Schwefeldiimide S(NR), mit R = Alkyl-, Aryl-und Sulfonyl-Resten sind in gro-Oer Zahl bekannt'.,); sie leiten sich formal von dem in freier Form nicht bestandigen Schwefeldiimid, S(NH),, ab. Schwefeldiimide mit Organoelement-Substituenten wurden vor allem von Elementen der 4. Hauptgruppe erhalten; so existiert die vollstandige Reihe S(N -EMe,), (E = C, Si, Ge, Sn, Pb) 3). Die Verbindungen rnit Organoelement-Substituenten der 6. Hauptgruppe beschrlnken sich derzeit auf die Sulfenylderivate S(N -SR),4-6). Schwefeldiimide rnit Organoelement-Substituenten der 5 . Hauptgruppe, S(N -ER,),, wurden bisher nicht beschrieben; es gibt Chem.
