 abstract = {The reaction of MesPQCPh2 with the least sterically demanding N-heterocyclic carbene (NHC = IMe) results in formation of the ‘abnormal’ (C4 -substituted) 4-phosphino-NHC (1). In contrast, reaction with Me2IMe gives the unprecedented ‘normal’ C2 adduct, Me2IMe - P(Mes)QCPh2 (2). Particularly striking is the asymmetric and weak bonding of the NHC to the PQC moiety in 2. DFT calculations indicate that the PQC natural bond order in 2 (1.54) still reflects significant pi-character to the bond (cf. MesPQCPh2: NBO = 1.98). Further computational analysis suggests that p-delocalization into the remote C-phenyl substituents is key to stabilizing the NHC adduct.},
