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
