摘要：

The difluorine dications [Ph2P(CH2)(n)PPh2CF2](2+)(Br-)(2) with n=2, 3 have been synthesized by reacting Br2CF2 with the chelating ligands Ph2P(CH2)(n)PPh2 (dppe, n=2; dppp, n=3). The dications [Ph2P(CH2)(n),Ph2CF2](2+) were structurally characterized by x-ray analysis and NMR spectroscopy. The doubly charged species are formally derived from the cyclic carbones [Ph2P(CH2)(n)PPh2C] where two r ions are attached to the divalent C(0) atom. The transient mono addition cations [Ph2P(CH2)(n)PPh2CF2Br](+) were observed but could not be isolated. The bonding analyses of [Ph2P(CH2)(n)PPh2CF2](2+) and [Ph2P(CH2)(n),Ph2CF2](+) suggest that the P-C-P bonds should be considered as classical electron-sharing bonds. (C) 2016 Elsevier B.V.
