Strong metal-borane interactions in low-valent cyclopentadienyl rhodium complexes

The first examples of half-sandwich Rh( i ) complexes stabilized by borane coordination have been prepared and structurally characterized. As substantiated by NMR spectroscopy and single-crystal X-ray diffraction, the phosphine-borane ligand iPr 2 P-( o -C 6 H 4 )-BFxyl 2 1 [Fxyl = 3,5-(F 3 C) 2 C 6...

Summary:The first examples of half-sandwich Rh( i ) complexes stabilized by borane coordination have been prepared and structurally characterized. As substantiated by NMR spectroscopy and single-crystal X-ray diffraction, the phosphine-borane ligand iPr 2 P-( o -C 6 H 4 )-BFxyl 2 1 [Fxyl = 3,5-(F 3 C) 2 C 6 H 3 ] engages in tight η 3 -BCC or η 1 -B coordination, depending on the metal environment. Half-sandwich Rh( i ) complexes stabilized by η 3 -BCC or η 1 -B borane coordination.
