However, our previous results [31] confirm that the regenerated Sc(OTf)3 goes on to catalyze secondary 1,3- Brook rearrangement [38], affording iii as the major product prior to desilylation. Noteworthy is the Molecules 2017, 22, 1041 5 of 13 Carbonyl 1,2-addition with the bulky silicon...
They can be separated by thin-layer chromatographic technique with the former as the major product. Based on the density functional theory (DFT) calculation with the geometries optimized at the B97-D3/SVP level of theory [21], the cis-cup-form having three bis(3 ,5 ,5 -trimethylhexyl)...
