Biphenylic Bisphosphines through ortho-Metalation of Aryldiphenylphosphine Oxides
Diphenyl-(2-trifluoromethyl)phosphine oxide was metalated next to the diphenylphosphinoyl group with LITMP. Upon iodination and Ullmann coupling, the corresponding 3,3?-disubstituted bis(phosphine oxide) was obtained. When phenyllithium was used as metalating agent, aryl/phenyl group excha...
