Donor-acceptor interactions in tri(phosphonio)methanide dications [(Ph 3 P) 2 CP(X)Ph 2 ] 2+ (X = H, Me, CN, NCS, OH, Cl, OTf, F)

The impact of the strongly electron donating carbodiphosphorane moiety in the series of tri(phosphonio)methanide dications as triflate salts [(Ph P) CP(X)Ph ][OTf] (X = H, Me, CN, NCS, OH, Cl, OTf, F) deriving from [(Ph P) CPPh ][OTf] (19[OTf]) is presented. The influence of the introduced substitue...

Description
Summary:The impact of the strongly electron donating carbodiphosphorane moiety in the series of tri(phosphonio)methanide dications as triflate salts [(Ph P) CP(X)Ph ][OTf] (X = H, Me, CN, NCS, OH, Cl, OTf, F) deriving from [(Ph P) CPPh ][OTf] (19[OTf]) is presented. The influence of the introduced substituents X on the electronic structures of these dications is investigated by means of detailed NBO analysis, NMR spectroscopy and X-ray analysis.
