Kontrollierte Oligomerisierung von Lewis-Säure/Base-stabilisierten Phosphanylalanen [Controlled oligomerisation of Lewis acid/base stabilised phosphanylalanes]

Autor: Bodensteiner, Michael, Vogel, Ulf, Timoshkin, Alexey Y., Scheer, Manfred

Durch Feinabstimmung der Temperatur- und Lösungsmittelbedingungen gelingt die kontrollierte H2-Eliminierung aus dem Lewis-Säure/Base-stabilisierten Phosphanylalan 1 (siehe Schema). Das entstehende cyclo-Trimer 2 bildet durch weitere H2-Eliminierung

Unexpected Differences in the Coordination Behaviour of 1,2,4-Triphosphaferrocenes towards Cu Chloride

Autor: Deng, Shining, Schwarzmaier, Christoph, Vogel, Ulf, Zabel, Manfred, Nixon, John F., Scheer, Manfred

The coordination behaviour of 1,2,4-triphosphaferrocenes [FeCpR(5-P3C2tBu2)] [CpR = Cp (1), Cp (2)] towards CuI chloride is significantly influenced by the substitution pattern of the cyclopentadienyl ring attached to iron. The dimeric copper complex

N-Heterocyclic Carbenes in Lewis Acid/Base Stabilised Phosphanylboranes

Autor: Adolf, Ariane, Vogel, Ulf, Zabel, Manfred, Timoshkin, Alexey Y., Scheer, Manfred

The reactions of 2-borane-1,3,4,5-tetramethylimidazoline (BH3·NHCMe) with selected phosphane adducts of the Lewis acids B(C6F5)3 and Ga(C6F5)3 are studied. Among others, adducts (C6F5)3Ga·PH2Cp* (1a) and (C6F5)3B·PH2Cp* (2) are used as starting ma

Selective halogenation at the pnictogen atom in Lewis-acid/base-stabilised phosphanylboranes and arsanylboranes

Autor: Schwan, Karl-Christian, Adolf, Ariane, Vogel, Ulf, Thoms, Christine, Zabel, Manfred, Timoshkin, Alexey Y., Scheer, Manfred

The halogenation of Lewis-acid/base-stabilised phosphanylboranes ( 1a) and arsanylboranes ( 1b) with CX4 (X = Cl, Br) leads selectively to the substitution of both protons at the pentel atom and the new compounds [(CO)5W(X2PBH2·NMe3)] ( 2a: X = Cl,

An Unusual Bonding Situation in a Novel AuI-Phosphido Complex with a Planar Au3P3 Framework

Autor: Vogel, Ulf, Sekar, Perumal, Ahlrichs, Reinhart, Huniar, Uwe, Scheer, Manfred

Reaction of the mono-deprotonated derivative of [{Cp(CO)2Mo}2(-PH2)(-H)] (1) leads to the novel complex [{Cp(CO)2Mo}2(-H){3-P(H)Au(PPh3)}] (2). In contrast the reaction of the analogous Cr derivative [{Cp(CO)2Cr}2(-PH2)(-H)] (1a) leads under identica

Lewis Acid/Base Stabilized Phosphanylalane and -gallane [Lewis-Säure/Base-stabilisiertes Phosphanylalan und -gallan]

Autor: Vogel, Ulf, Timoshkin, Alexey Y., Scheer, Manfred

Neither synthesis nor detection in matrix isolation experiments has been accomplished for the parent compounds of phosphanylalanes and -gallanes of type A. H2 elimination reactions between [(CO)5WPH3] and H3ENMe3 (E=Al, Ga) have enabled the first syn
