TLDR
The diaryldilithiosilane thus generated was found to be stable at −78 °C but undergo an intramolecular proton abstraction to give the lithium-migrated dilithio-ilane as mentioned in this paper.Abstract:
Exhaustive reduction of dibromo(2,6-diisopropylphenyl){2,4,6-tris[bis(trimethylsilyl)methyl]phenyl}silane with excess amount of lithium naphthalenide (more than 4 molar amounts) in tetrahydrofuran at −78 °C gave the corresponding dilithiosilane, the effective formation of which was confirmed by the trapping experiments with a variety of electrophiles. The diaryldilithiosilane thus generated was found to be stable at −78 °C but undergo an intramolecular proton abstraction to give the lithium-migrated dilithiosilane.1read more

Recent advances in the chemistry of group 14-group 16 double bond compounds
Norihiro Tokitoh,Renji Okazaki +1 more
TL;DR: In this article, the authors discuss the remarkable progress in the chemistry of heavy ketones leading to the systematic comparison of their structures and properties that are capable of existence as stable species if their highly reactive M=X bond is adequately protected toward dimerization.
