Über Pentafluorphenyl-Verbindungen der V. Hauptgruppe V

Abstract: Die IR-Spektren der Verbindungen CgF5PX2 (X = H, CHS, Cl, Br), Tris (pentafluorphenyl) -phosphin und Tris (pentafluorphenyl) phosphinoxyd im Bereich 4000 > v(cm -1 )> 300 werden mitgeteilt und nach Gruppenfrequenzen zugeordnet.Der Frequenzgang der PO-Valenzschwingung in der Reihe Rn(C6F5)3_nPO (R = CH3 , C2H5 , C6H5) wird eingehend diskutiert.Während über Ultrarot-und Raman-Spektren von Phenylderivaten des Phosphors eine große Anzahl von Publikationen vorliegen, sind von Pentafluorphenyl-Verbindungen der V. Ha… Show more

“…The reaction of PBiP-C 6 F 5 with [PtCl 2 (cod)] in THF or dichloromethane (Scheme ) led to a light yellow, insoluble solid, too. Absorption bands for the C–C stretching vibrations of the pentafluorophenyl residue were present in the IR spectra at 1631 (w), 1503 (vs), and 1460 (vs) cm –1 and for the C–F stretching vibrations at 1346 (vs), 1064 (vs), and 960 (vs) cm –1 …”

“…[22] However, only a broad singlet was observed (w 1/2 ϭ 39Ϫ40 Hz), as opposed to the fluorinecoupled pseudoquintuplet (J PF ϭ 35 Hz) of the free phosphane.…”

“…However, the 31 P NMR spectrum showed mainly P(C 6 F 5 ) 3 (δ ϭ Ϫ74.2; 73%), and one new signal that was assigned to the oxide OϭP(C 6 F 5 ) 3 (δ ϭ Ϫ7.9; 27%) based upon the close agreement with the chemical shift in the literature (δ ϭ Ϫ7.8). [22] Reactions were attempted in the absence of solvent. Complex 1 and P(C 6 F 5 ) 3 melt at 119 and 107°C, respectively, and were kept at 140°C (1.0:1.3 molar ratio) for 10 h. During this time, some of the P(C 6 F 5 ) 3 sublimed to the top part of the flask not immersed in the oil bath.…”
