reaction between 2 and [Ni(COD)2] gave a pincer complex [NiBr2,6-Ph2PC(O)}2(C6H3)}] (8), whereas the 2 : 1 reaction of 2 with [Pd2(dba)3] yielded the palladium analogue [PdBr2,6-Ph2PC(O)}2(C6H3)}] (9) in quantitative yield. The reaction between 1 and CuX in a 1 : 1 molar ratio produced binuclear complexes, [Cu2(μ-X)21,3-Ph2PC(O)}2(C6H4)}2] (10, X = Cl; 11, X = Br; 12, X = I), whereas the reaction
