On the compatibility of Ruthenium metathesis catalysts with secondary phosphines

Van Lierop, Bianca J.,Fogg, Deryn E.

, p. 7245 - 7248 (2013)

While attempts to incorporate secondary phosphine ligands into the first-generation Grubbs catalyst RuCl2(PR3) 2(=CHPh) (GI, R = Cy) were frustrated by decomposition (for HPCy 2) or bulk (for HPtBusu

Reactivity of Phosphanylphosphinidene Complex of Tungsten(VI) toward Phosphines: A New Method of Synthesis of catena-Polyphosphorus Ligands

Grubba, Rafa?,Ordyszewska, Anna,Kaniewska, Kinga,Ponikiewski, ?ukasz,Chojnacki, Jaros?aw,Gudat, Dietrich,Pikies, Jerzy

, p. 8380 - 8387 (2015/09/21)

The reactivity of an anionic phosphanylphosphinidene complex of tungsten(VI), [(2,6-i-Pr2C6H3N)2(Cl)W(η2-t-Bu2P=P)]Li·3DME toward PMe3, halogenophosphines, and iodine was investigated. Reaction of the starting complex with Me3P led to formation of a new neutral phosphanylphosphinidene complex, [(2,6-i-Pr2C6H3N)2(Me3P)W(η2-t-Bu2P=P)]. Reactions with halogenophosphines yielded new catena-phosphorus complexes. From reaction with Ph2PCl and Ph2PBr, a complex with an anionic triphosphorus ligand t-Bu2P-P(-)-PPh2 was isolated. The main product of reaction with PhPCl2 was a tungsten(VI) complex with a pentaphosphorus ligand, t-Bu2P-P(-)-P(Ph)-P(-)-P-t-Bu2. Iodine reacted with the starting complex as an electrophile under splitting of the P-P bond in the t-Bu2P=P unit to yield [(1,2-η-t-Bu2P-P-P-t-Bu2)W(2,6-i-Pr2C6H3N)2Cl], t-Bu2PI, and phosphorus polymers. The molecular structures of the isolated products in the solid state and in solution were established by single crystal X-ray diffraction and NMR spectroscopy. (Chemical Equation Presented).
