Formation of a diphosphine: Synthesis and molecular structure of bis(tetraphenylbutadienyl)diphosphine, (Ph4C4)P-P(C4Ph4)

Reaction of 1,4-dilithiotetraphenylbutadiene with phosphorus(III) bromide affords bis(tetraphenylbutadienyl)diphosphine, (Ph4C4)P-P(C4Ph4), with a phosphorus-phosphorus bond length of 2.2051(11) A.

Synthesis of phospholes and 1,1′-biphospholes mediated by zirconacyclopentadienes and PBr3

The efficient synthesis of phospholes through the reactions of Grignard reagents with in situ-generated 1-bromophospholes has been developed. This method allows the easy substituent variation at the phosphorus atom of the phospholes. The 1,1′-biphospholes can also be conveniently prepared through Zn-promoted debromo-dimerization of 1-bromophospholes. The gold-phosphole complexes of LAuCl were also synthesized, which were found to act as efficient catalysts in gold-catalyzed [3+2] cycloaddition of ynamides with 4,5-dihydro-1,2,4-oxadiazoles.
