Zur Komplexbildung von Silylphosphanen

Abstract: me2Si[P(Sime3) (Cme3)]2 1 (me = CH3) reagiert mit Ni(CO)4 zu 5 (Konfigurationsisomere im Verh. 1:1). Die 1,3‐Disila‐2, 4‐diphospha‐cyclobutane 2 und 3 bilden mit Ni(CO)4 bzw Cr(CO)5. THF die Verbindungen 6 und 7. Die Umsetzung von 3 mit 2 Mol Ni(CO)4 führt zum Zweikernkomplex 8.

“…153,154 The nickel complex 406 forms two isomers in a ratio of 1:1. 155 Monocyclic silylphosphanes as [Me 2 Si-PtBu-SiPh 2 -PtBu] (333) and [Me 2 Si-PtBu] 2 (329) react with Ni(CO) 4 , depending on the molar ratio to the nickel complex 407 or to the dinuclear complex 407a, respectively (Scheme 27). Both compounds are decomposed either by light or when stored in vacuo.…”

“…Compound 408 is more stable than the nickel complex 407. 155 In the triphosphatrisilacyclohexane 304 the ring skeleton allows the coordination of a Mo(CO) 3 group to the three P atoms of the six-membered ring according to (126). 115 Furthermore, various derivatives of 1,3,5-triphospha-2,4,6-trisilacyclohexanes were synthesized (127) to study the sterical influence of the Si substituents.…”

“…FRITZ, 1,3,5,7-Tetraphospha-S, 4,6,8,9-dekamethyl-2,4,6,8,9- (7) FRITZ, 1,3,5,7-Tetraphospha-2,4,G,8,9-dekamethyl-2,4,6,8,9-pentasilabicyclo(3.3.1) Chelatliganden bedingen oft eine groljere 31P-Feldverschiebung als offenkettige Verbindungen, was mit der starkeren Winkelveranderung bei der Koordination erklart wird [7]. Zu beachten ist die Tieffeldverschiebung fur die Bruckenkopfphosphorahome, die nicht direkt am Metall koordiniert sind, die jedoch auch an anderen Phosphorkomplexen zu beobachten waren [8]. Die Kopplungskonstante JPH = 286 Hz in 2 ist gegenuber 1 im Mittel um 96 Hz grol3er.…”
