The substituent on boron allows the electronic nature of the heterocycle of B ‐heteroatom‐substituted (R=H, O, S, N, P, and F) 1,2‐azaborolyl complexes to be modulated. Given that 1,2‐azaborolyl is isoelectronic with cyclopentadienyl (see scheme), one of the most widely used ligands in organometallic chemistry, it seems likely that the diverse array of compounds synthesized in this study will stimulate the development of applications of η 5 ‐(1,2‐azaborolyl) ligands in metal‐catalyzed processes.
