NMR Spectrum
Prediction： Figure 1: A signal in the vicinity of delta = 128.0-135.0 ppm assigned to the phenyl group inPhSi(OMe)3 and a signal in the vicinity of delta = 50.5 ppm assigned to the methoxy group inPhSi(OMe)3 arepresent Figure 7: Signals for the unreacted starting materials are observed, but the signals agree with Figure 1 and Figure 6 and the same product can therefore be confirmed. A signal in the vicinity of delta = 128.0-134.9 ppm assigned to the phenyl group in PhSi(OMe)3 and a signal in the vicinity of delta = 50.8 ppm assigned to the methoxy group in PhSi(OMe)3 are present Figure 9: Considering the signals other than those for the starting materials, the signal shapes are about the same as in Figure 1 and the product is therefore the same. A signal in the vicinity of delta = 127.6-134.8 ppm assigned to the phenyl group in PhSi(OMe)3 and a signal in the vicinity of delta = 50.7 ppm assigned to the methoxy group in PhSi(OMe)3 are present
