Ma. Bennett et al., REGIOSPECIFIC SYNTHESIS OF 2,3-NAPHTHYLENEBIS(DIPHENYLPHOSPHINES) BY DOUBLE INSERTION OF ALKYNYLPHOSPHINES INTO NICKER(0)-BENZYNE COMPLEXES, Chemical communications, (12), 1998, pp. 1307-1308
The double insertion of diphenylprop-1-ynylphosphine into the nickel(0
)-benzyne bond of the complexes [Ni(1,2-eta-4,5-X2C6H2)(PEt3)(2)] (X =
H, F) forms 2,3-naphthylenebis(diphenylphosphines) regiospecifically.
