| Abstract: | Reactions of Ferrocenol and 1,1′-Ferrocendiol with Cyclotriphosphazenes, P3N3F6 and P3N3Cl6 The 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 ). 1 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. |
