In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Precious metal-phosphine complexes for homogeneous catalysis: synthesis and characterization of a complete series of (dppf)MX2 (M = Pt, Pd; X = Cl, Br, I, Ph), published in 1999-03-31, which mentions a compound: 12266-72-7, mainly applied to phosphinoferrocene palladium platinum halide complex preparation; ferrocenylphosphine palladium platinum halo complex preparation, Application of 12266-72-7.
(PPh2C5H4)2Fe (dppf) complexes of PdX2 (X = Cl, Br) and PtX2(X = Cl, Br, I, Ph) have been synthesized in nearly quant. yield with excellent purity by reacting the resp. norbornadiene or 1,5-cyclooctadiene metal complexes with dppf. The palladium iodide complex, (dppf)PdI2 has been isolated in 98% yield by a 1:2 mol reaction of (dppf)PdCl2 with NaI. Methods have been developed to isolate these complexes with and without the solvent (usually CH2Cl2) in the lattice. These compounds have been characterized by elemental, FTIR, multi-nuclear FTNMR and in some cases by previously reported single crystal X-Ray diffraction.
Compounds in my other articles are similar to this one(Diiodo(1,5-cyclooctadiene)platinum(II))Application of 12266-72-7, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
