A New Phosphinite Chelate, (aryl)2POBF2OH, Complexed to Ruthenium(II). HBF4-Induced P−C Bond Cleavage in Chiral MeO-Biphep Complexes

Reaction of Ru(OAc)2(MeO-Biphep) (MeO-Biphep = 6,6‘-dimethoxybiphenyl-2,2‘-diylbis(diarylphosphine)) with 2 equiv of HBF4 in CH2Cl2 cleaves the MeO-Biphep. Products contain the exotic chelate ligand (aryl)2POB(OH)F2 (aryl = phenyl, p-tolyl, 3,5-di-tert-butylphenyl) together with an (aryl)2P−η6-arene...

Summary:Reaction of Ru(OAc)2(MeO-Biphep) (MeO-Biphep = 6,6‘-dimethoxybiphenyl-2,2‘-diylbis(diarylphosphine)) with 2 equiv of HBF4 in CH2Cl2 cleaves the MeO-Biphep. Products contain the exotic chelate ligand (aryl)2POB(OH)F2 (aryl = phenyl, p-tolyl, 3,5-di-tert-butylphenyl) together with an (aryl)2P−η6-arene, 8e donor chelate. The reaction involves a fluorophosphine intermediate.
