Metallkomplexe des Hexamethyl‐trisila‐tetraphospha‐nortricyclen P4 (Sime2)3

Abstract: Die Titelverbindung P4(Sime2)3 1 bildet mit Mo(CO)6, Cr(CO)5THF und Mn(η‐C5H5)(CO)2THF kristalline Komplexverbindungen, in denen 1 als einzähniger Ligand mit einem P‐Atom des P‐Dreiringes as das Metall Koordiniert ist. Mit Mn(η‐C5H5)(CO)2 THF lassen sich auch zwei Mn(η‐C5H5)(CO)2‐Gruppen an 1 koordinieren, Wobei die Bindung über je ein P‐Atom des P‐Dreiringes erfolgt. Mit Cr(CO)4‐Norbornadien reagiert 1 unter Dimerisierung zum (CO)4Cr[μ‐P 4(Sime3)3]2Cr(CO)4(rote Kristalle). Die beiden Moleküle von 1 sind ü ber… Show more

“…The products were identified by NMR investigations, mass spectra as well as elemental analysis. 159 Additional single crystal X-ray analyses of the chromium complexes P 4 (SiMe 2 ) 3 Cr(CO) 5 ( 420) and [P 4 (SiMe 2 ) 3 Cr(CO) 4 ] 2 (423) demonstrated that only minor changes in the bond distances were caused by the chromium fragment. 160 An even higher coordination of the Cr moiety by 379 can be achieved with chromium complexes which contain a triply coordinated ligand (130).…”

“…190b The Si-P bond in [(F 3 C) 2 P] 2 P-SiMe 3 (467) cannot be cleaved, not even by BuLi. 189 The direct way via the Si-P bond cleavage in (tBu 2 P) 2 P(SiMe 3 ) (236) with different halogenating agents, such as for instance N-bromosuccinimide (NBS) (159), offers another possibility for synthesizing the phosphinophosphinidene phosphorane 460.…”
