Rhodium(III) Complexes Featuring Coordinated CF3 Appendages

Abstract

The synthesis and characterisation of a homologous series of rhodium 2,2'-biphenyl complexes featuring intramolecular dative bonding of the nominally inert and weakly coordinating trifluoromethyl group are described. Presence of these interactions is evidenced in the solid state using X-ray diffraction, with RhÀF contacts of 2.36-2.45 , and in solution using NMR spectroscopy, through hindered CÀCF 3 bond rotation and the presence of timeaveraged
