文摘

Dialkylbiarylphosphines are an emerging ligand set that promote catalytic reactions of electrophilic late transition-element centers through dative interactions of the biaryl arm with the metal site. Presented here are syntheses and crystal structures of five new (dicyclohexylbiarylphosphine)gold(I) chlorides and bromides. X-ray diffraction crystallography reveals close approaches between gold(I) and the flanking ipso carbon (mean Au−C_ipso distance, compounds 2−6: 3.156 Å). New compounds have been characterized by multinuclear NMR spectroscopy, X-ray diffraction crystallography, and combustion analysis.
