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′-dilbis (diphenylphosphine)(1)) can be conveniently prepared by Ullmann coupling of 2-iodophenyldiphenylphosphine oxide and subsequent reduction ...
