C–H functionalization of tetramethylsilane employing a borylnitrene

Abstract

The irradiation of 2-azido-4,4,5,5-tetramethyl-1,3,2-dioxaborol (pinBN₃, pin = pinacolato) generates the corresponding borylnitrene that easily inserts into the CH bond of tetramethylsilane. This primary photoproduct, a monoborylated aminoborane, undergoes a subsequent reaction with pinBN₃ forming a bisborylated aminoborane.
