All reactions involving air-sensitive
compounds were carried out under an atmosphere of dry nitrogen or
argon using either Schlenk techniques or a glovebox. All solvents
were dried using a column-based solvent purification system.39 Compounds1 , 2 , and 7 were prepared according to previously published procedures.1 (link) All other chemicals were obtained from different
suppliers and used without further purification.
1H (300 MHz), 13C (75.4 MHz), and 29Si (59.3
MHz) NMR spectra were recorded on a Varian INOVA 300 spectrometer.
If not noted otherwise, for all samples benzene-d6 was used or, in the case of reaction samples, they were
measured with a water-d2 capillary in
order to provide an external lock frequency signal. To compensate
for the low isotopic abundance of 29Si, the INEPT pulse
sequence was used for the amplification of the signal.40 ,41 Elemental analysis was carried out using a Heraeus VARIO ELEMENTAR
instrument.
