Synthesis, Characterization and Properties of Transition Metal Pd/Pt [60]Fullerene Complexes Containing Phosphane Ligands − Crystal Structure of [Pd(η2‐C60){Ph2PCH2(CH2OCH2)2CH2PPh2}]

“…Other solvents were bubbled with nitrogen for at least 20 minutes before use. Pd(dba) 2 , [19] Pd 2 (dba) 3 , [20] P(Fc) 3 , [21] P(Fc) 2 Ph, [22] P(Fc)Ph 2 , [22] PPh 2 H, [23] P(2-Fu) 3 , [24] P(2-Fu)Ph 2 [25] and Pt(dba) 2 [26] were prepared according to literature methods. C 60 (99.9%) is available commercially.…”

A Wittig Reaction with 2-Furyl Substituents at the Phosphorus Atom: Improved (Z) Selectivity and Isolation of a Stable Oxaphosphetane Intermediate

“…As objects for further systematic investigations, 2‐furyl substituents were selected, since we reasoned that the electronegative oxygen atom should be better suited for complexing lithium ions, and this should mean greater betaine stability than in the pyridyl case. Two studies involving 2‐furyl systems in Wittig reactions have been published,15,16 but only the work of Schlosser et al dealt with influences of 2‐furyl groups on the stereoselectivity of the reaction, and in neither case was information about reaction intermediates given.…”

Synthesis of P-chiral phosphines via chiral metal template promoted asymmetric furan Diels–Alder reaction

“…2-Diphenylphosphinofuran [10] and phenyldivinylphosphine [11] were prepared according to standard literature methods. The dimeric platinum complexes (S)-and (R)-1 were prepared by the method previously reported by our group [3b].…”
