AN IMPROVED SYNTHETIC METHOD FOR DIPHENYL-1-PYRENYLPHOSPHINE AND THE PROPERTIES AND STRUCTURE OF ITS BORANE ADDUCT

An efficient synthetic method for diphenyl-1-pyrenylphosphine, DPPP, has been developed involving a low temperature Li-Br exchange reaction using the commercially available 1-bromopyrene. An estimate of the donor ability of this phosphine has been obtained by measuring the A 1 υ (CO) band of the Ni(...

Summary:An efficient synthetic method for diphenyl-1-pyrenylphosphine, DPPP, has been developed involving a low temperature Li-Br exchange reaction using the commercially available 1-bromopyrene. An estimate of the donor ability of this phosphine has been obtained by measuring the A 1 υ (CO) band of the Ni(CO) 3 L complex which was found to be 0.4 wave numbers lower than that from the PPh 3 complex indicating that DPPP is a slightly better donor than PPh 3 . The BH 3 adduct of DPPP has been prepared and, as the situation for the oxide of DPPP, this adduct is fluorescent. It is estimated that the fluorescence intensity is about half that of DPPPO. An x-ray structure of this adduct has been obtained, and the bond lengths and angles appear to be in expected ranges.
