Contrasting Reactivity of (Boryl)(Aryl)Lithium-Amide with Electrophiles: N- vsp-Aryl-C-Nucleophilic Substitution

Abstract

Herein we report two different reactivity modes of lithium(aryl)(boryl)amide, 3 when it is reacted with chlorosilanes such as SiCl4 and MeSiHCl2, and chlorophosphine, Ph2PCl. Thus, the reaction of lithium(aryl)(boryl)amide, 4 with MeSiHCl2 leads exclusively to a N-substitution product, 6. On the other hand, the reaction of 4 with SiCl4 and Ph2PCl proceed completely differently affording exclusive p-aryl-C- substitution products, 5 and 7, respectively.
