Unusual 1,3-rearrangement of trimethylsilyl group in the reaction of 2,4,6-tris[bis(trimethylsilyl)methyl]phenyllithium

Add time:08/04/2019    Source:sciencedirect.com

2,4,6-Tris[bis(trimethylsilyl)methyl]phenyllithium (TbLi) gave a novel 1,3-silicon rearrangement product above −30 °C, while the treatment of TbLi with some electrophiles also afforded 1,3-silicon rearrangement products even at −78 °C probably via single electron transfer mechanism.
