A unique family of N-heterocycliccarbenes derived from bioxazolines (IBiox) suitable for application in transition-metal catalysis is described. The ligands are electron rich, sterically demanding, and have restricted flexibility. Their usefulness has been demonstrated in the Suzuki-Miyaura cross-coupling of stericallyhinderedarylchlorides and boronic acids. For the first time, tetraortho-substituted

Green and sustainable access to chiral and achiral gold-IBiox complexes is reported. %Vbur for the Au-IBiox complexes were calculated for the first time from XRD data. Their catalytic activity was examined in the hydroamination of phenylacetylene.
