NMR spectroscopy and elemental analysis

NMR spectra were recorded on a Bruker DPX 400 NMR spectrometer, operating at

400.13 MHz for 1H, 155.5 MHz for 7Li and 100.6 MHz for 13C. 1H and 13C{1H} spectra

were referenced to the appropriate solvent signal, 7Li NMR spectra were referenced

against LiCl in D2O at 0.00 ppm. Elemental analyses of the compounds 1 – 11 were

carried out using a Perkin Elmer 2400 elemental analyser.

NMR spectroscopic studies1H DOSY-NMR Analysis details. Diffusion-Ordered SpectroscopY (DOSY) NMR

experiments were performed on a Bruker AVANCE 400 MHz NMR spectrometer at

25ºC operating at 400.13 MHz for 1H under TopSpin (version 2.0, Bruker Biospin,

Karlsruhe) and equipped with a BBFO-z-atm probe with actively shielded z-gradient

coil capable of delivering a maximum gradient strength of 54 G cm -1. Diffusion-

ordered NMR data were acquired using the Bruker pulse program dstegp3s with a

double stimulated echo with three spoiling gradients. Sine-shaped gradient pulses

were used with a duration of 4 ms together with a diffusion period of 100 ms.

Gradient recovery delays of 200 μs followed the application of each gradient pulse.

Data were systematically accumulated by linearly varying the diffusion encoding

gradients over a range from 2% to 95% of maximum for 64 gradient increment

values. The signal decay dimension on the pseudo-2D data was generated by

Fourier transformation of the time-domain data. DOSY plot were generated by use of

the DOSY processing module of TopSpin. Parameters were optimized empirically to

find the best quality of data for presentation purposes. Diffusion coefficients (D) were

calculated by fitting intensity data to the Stejskal-Tanner expression. The external

standard was tetramethylsilane, and we used the external calibration curves method

recently published by Stalke.[1] The molecular weight (MW) was estimated by DOSY-

NMR using the diffusion coefficients for the signals corresponding to the species

present in solution.
