The first stable 9-anthryldiphosphene, TbtP=P(9-Anth) (1: Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl, 9-Anth = 9-anthryl), was synthesized and its properties were revealed by spectroscopic and X-ray crystallographic analyses. The weak fluorescence of 1 was observed in hexane solution.
the electronic communication between the anthryl moiety and the P=P unit. It was found that TbtP=P(9-Anth) (1a: 9-Anth = 9-anthryl) showed weak fluorescence in hexane solution. Furthermore, the reactivities of anthryldiphosphene 1 with a chromium complex, chalcogenation reagents, a diene, and electron-deficient olefins have been revealed.
[Ar = Ph, 2,4,6-trimethylphenyl (Mes), 9-anthryl (Ant)] leads to the formation of binuclear nickel(II) complexes with bridging ArP(H)O2− ligands. Crystal structures of the binuclear complexes [Ni2(μ-O2P(H)Ar)2(bpy)4]Br2 (Ar = Ph, Mes, Ant) have been determined. In each structure, the metal ions have distorted octahedral coordination and are doubly bridged by two arylphosphinato ligands. Magnetic susceptibility
The invention relates to a process for synthesizing tertiary phosphines by reacting halophosphines with organomagnesium compounds in the presence of copper compounds and optionally of salts.
An intramolecular [4+2] cycloaddition of 1-(9-anthrylchlorophosphino)-1,4-diphenylbut-1-en-3-yne produced the 1-(chlorophosphino)-1,4-diphenyl-1,3-butadiene derivative incorporated with a dibenzoba...
