REVEALING THE REACTIVITY OF MYSTERIOUS SILYLONES

摘要

First predicted and prepared in 2009 and 2013, respectively, silylones, also known as siladicarbenes, are compounds containing zero-valent silicon coordinated to two carbene ligands. Silylones feature strong Si-C bonds strengthened by a three-center two-electron π-bond, making them much less reactive than carbodicarbenes, their lighter analogues, and the reactivity of silylones therefore remains completely unknown.
