We report here a set of triaryl pyrazole based B-N coordinated boron compounds (11-17) synthesized by electrophilic aromatic borylation strategy. All the pyrazole boron compounds were thoroughly characterized using multinuclear NMR spectroscopy, LC-MS, and single crystal X-ray diffraction analysis (for 12-17). The photoluminescence measurements of 11-17 revealed that the emission peak maxima were tuned based on the substitution on N-phenyl.

The related water adducts are also included. The [(NHC)M]+(M = Cu, Ag, Au) species show the noteworthy ability to bind Et2O and H2O.

A comparison of [(SIPr)Au-Fe(CO)][SbF], [(CAAC)Au-Fe(CO)][SbF] and [(MesP)Au-Fe(CO)][SbF] shows that the ligand donor strength towards Au(i) follows the order MesP > CAAC > SIPr. These Fe(CO) complexes show significant blue shifts in [small nu, Greek, macron] bands relative to those observed for free Fe(CO) as a result of it serving as a net electron donor to Au(i).
