Regiospecific synthesis of 2,3-naphthylenebis(diphenylphosphines) by double insertion of alkynylphosphines into nickel(0)–benzyne complexes
Abstract
The double insertion of diphenylprop-1-ynylphosphine into the nickel(0)–benzyne bond of the complexes [Ni(1,2-η- 4,5-X2C6H2)(PEt3)2] (X = H, F) forms 2,3- naphthylenebis(diphenylphosphines) regiospecifically.
