摘要：

The reaction between 2,2'-dilithiobiphenyl and two equivalents of chlorodiphenylphosphine is confirmed to afford equal amounts of 9-phenyl-9-phosphafluorene (2) and triphenylphosphine. 2,2'-Bis(diphenylphosphino)biphenyl (1,1'-biphenyl-2,2'-diylbis(diphenylphos phine) (1)) can be conveniently prepared by Ullmann coupling of 2-iodophenyldiphenylphosphine oxide and subsequent reduction with trichlorosilane.
