Stepwise BN bond cleavage by isocyanides: access to the 3-azaborole structural motif

Key Points

The research investigates the stepwise cleavage of the BN bond using isocyanides to create 3-azaborole structures.
Conducted a [2+1+1] cycloaddition reaction with isocyanides
Performed reductive insertion of a third isocyanide into the BN bond
Characterized the resulting 3-azaborole structure
Successfully synthesized 3-azaborole diide
Observed significant charge delocalization onto the o-carborane framework
Confirmed the mechanism through experimental data

Abstract

TheBN bond undergoes a 2+1+1 cycloaddition with two equiv of isocyanide, followed by reductive insertion of a third isocyanide into the BN bond, affording a 3-azaborolediide with pronounced charge delocalization onto the o -carborane framework.
