Supplementary Material (ESI) for Chemical Communications

General Methods. All manipulations were performed under a nitrogen atmosphere using standard Schlenk techniques or an MBraun glovebox. All solvents were purified from an MBraun SPS system. Samples of scandium complexes for NMR spectroscopic measurements were prepared in the glovebox by use of NMR tubes sealed by paraffin film. H, C, and P NMR spectra were recorded on a Bruker AV600 (FT, 600 MHz for H; 150 MHz for C) spectrometer. NMR assignments were confirmed by H–H COSY and H–C HMQC experiments when necessary. Elemental analysis was performed at National Analytical Research Centre of Changchun Institute of Applied Chemistry (CIAC). 2,6-diisopropylaniline was dried over CaH2
