Perfluorophenyl groups

Perfluoro- rt,4 -phenylene mercury, as anion acceptor, 2, 451 Perfluoro- rt,4 -phenylenes, with mercury, 2, 456-457 Perfluorophenyl groups, in a-organonickel complexes, 8, 33 Perfluorophenyl ligation, and monomeric Cr(III) derivatives,... 

Fig. 11. The heteroelement framework of l(C6F5)2Ge] jBi2. Only the a-carbon of the perfluorophenyl groups is included for simplicity.

Trlmethyl(perfluorophenyl)silane undergoes the same characteristic reactions as trimethyl(tri-fluoroinethyl)silane. Thus, perfluorophenyl groups can be introduced at multiple bonds (C = C, C = N, etc.) with active halogen atoms, e.g. formation of 17 and 18. ... 

The perfluorophenyl derivatives of the elements of Group V (P, As, Sb. Bi) are elTectivc sources of the three perfluorophenyl groups bonded with the elements, under the conditions of catalysis by fluoride ion. 

The face-to-face stacking interaction between phenyl and perfluorophenyl groups was used to orient olefinic molecules and to cocrystallize them [51]. The... 

A later study" shows, however, that the lower-frequency band near 2750 cm must be assigned to p(CH xo), since replacement of the exo hydrogen by the phenyl or perfluorophenyl group results in the disappearance of this band. In the case of Mn(C6H7)(CO)3, the bands at 2970 and 2830 cm were assigned to p(CH, do) and p(CHexo), respectively. Vibrational frequencies have... 

Alternatively, /( P- Pt) couplings have been observed for compounds containing a Pt-M-PPhs unit (M = Ag, Au) [20, 21]. The formation of Pt°-Cd° or Pt -Ag interactions in solution has been found to cause a downlield shift of the Pt resonance [22, 23]. The presence of Pt -M bonds in solution also manifests itself indirectly in several ways, for example by a decrease of the /( H- Pt) coupling constant of platinum-bound methyl groups [20, 24, 25] or the appearance of coupling between the acceptor metal nucleus and the ortho fluorine atom of platinum-bound perfluorophenyl groups [26].
