    Description / Table of Contents: Reactions of Ferrocenol and 1,1′-Ferrocendiol with Cyclotriphosphazenes, P3N3F6 and P3N3Cl6The hexahalogeno-cyclotriphosphazenes, P3N3X6 (X = F (1 a), Cl (1 b)), react with ferrocenol (FcOH) in a molar ratio 1 : 1 to give the ferrocenoxy derivatives, FcO[P3N3X5] (X = F (3 a), Cl (3 b)); in an analogous manner the tetrameric ring P4N4Cl8 (2 b) is converted to FcO[P4N4Cl7] (4 b). Abkürzungen: Fc = Ferrocenyl, (C5H5)Fe(C5H4-); fc = 1,1′-ferrocendiyl, Fe(C5H4-)2; rc = 1,1′-ruthenocendiyl, Ru(C5H4-)2. Fluorphosphazene werden mit a, Chlorphosphazene mit b gekennzeichnet. With 1,1′-ferrocenediol, (fc(OH) 2), the cyclo triphosphazenes react in a molar ratio 1 : 1 to produce fcO 2[P 3 N 3 X 4] (X = F ( 5 a), Cl ( 5 b)). According to the x-ray structure analysis, the 1,1′-ferrocenediolato group in 5 a , b is bound to two different phosphorus atoms. On the contrary, the 1,1′-ferrocenedithiolato- and 1,1′-ferrocenediselenolato units in fcS 2[P 3 N 3 X 5] (X = F ( 6 a), Cl ( 6 b)) and fcSe 2[P 3 N 3 X 5] (X = F ( 7 a), Cl ( 7 b)) are attached to only one phosphorus atom, and spirocyclic 1,3-dichalcogena-2-phospha-[3]ferrocenophanes are formed. All new products have been characterized on the basis of their 1 H, 13 C and 31 P NMR as well as EI mass spectra. The molecular structures of 5 a , b and 6 a have been determined by x-ray structure analyses.
    Notes: Die Hexahalogen-cyclotriphosphazene, P3N3X6 (X = F (1 a), Cl (1 b)), reagieren mit Ferrocenol, FcOH, im Molverhältnis 1 : 1 unter Bildung der Ferrocenoxy-Derivate FcO[P3N3X5] (X = F (3 a), Cl (3 b)); der tetramere Ring P4N4Cl8 (2 b) bildet in analoger Weise FcO[P4N4Cl7] (4 b). 1,1′-Ferrocendiol, fc(OH)2, setzt sich mit P3N3X6 im Molverhältnis 1 : 1 zu fcO2[P3N3X4] (X = F (5 a), Cl (5 b)) um; nach der Röntgenstrukturanalyse ist der 1,1′-Ferrocendiolato-Rest in 5 a, b an zwei verschiedene Phosphoratome gebunden. Dagegen werden die 1,1′-Ferrocendithiolat- und 1,1′-Ferrocendiselenolat-Reste in fcS2[P3N3X4] (X = F (6 a), Cl (6 b)) bzw. fcSe2[P3N3X4] (X = F (7a), Cl (7 b)) jeweils nur an ein Phosphoratom angekoppelt, so daß spirocyclische 1,2-Dichalkogena-2-phospha[3]ferrocenophane entstehen. Alle neuen Produkte wurden anhand ihrer 1H-, 13C- und 31P-NMR-Spektren und der EI-Massenspektren charakterisiert; für 5 a, b und 6 a wurde die Molekülstruktur durch Röntgenstrukturanalyse bestimmt.
