Convenient Access to a N,N’‐bis(2,6‐terphenyl) Substituted N‐Heterocyclic Carbene

The efficient synthesis of a N , N’ ‐bis(2,6‐terphenyl) substituted N ‐heterocyclic carbene (NHC) is reported. The gain in efficiency and total yield, compared to traditional synthesis, is the result of a high yielding and scalable double Suzuki coupling step, affording a 2,6‐terphenyl aniline, catalyzed by a Pd β‐diketiminate complex. A stereoelectronic study revealed the new NHC to be very similar to the only other N , N’ ‐bis(2,6‐terphenyl) substituted NHC. Application to the stabilization of Group 13 trihydrides gives acceptable outcomes but inferior to those observed when the bulky IPr* NHC is deployed.
