Sterically demanding and conformationally stableN,N′-ditertiaryalkyl-N,N′-diphenyl acyclicdiaminocarbenes (ADCs) were developed. Bulky ADC−Au catalysts not only showed competitive reactivities in hydroamination and enyne cyclization but also demonstrated unique ligand properties different from bulky N-heterocyclic carbene (NHC) counterparts.
