Recommanded Product: 12266-72-7. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Diiodo(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12I2Pt, CAS is 12266-72-7, about Synthesis and structure of platinum(II)- and palladium(II)-phosphorin complexes in solid and solution state. Author is Shiotsuka, Michito; Tanamachi, Takahiro; Urakawa, Tsuyoshi; Matsuda, Yoshihisa.
The novel platinum and palladium complexes with phosphorin, [Pt(dmppn)2X2] (X = Cl, 1; Br, 2; I, 3) and [Pd(dmppn)2X2] (X = Cl, 4; Br, 5), were prepared using 4,5-dimethyl-2-phenylphosphorin (dmppn) with M(cod)X2 or M(PhCN)2X2 (M = Pt, Pd). The crystal structure of 3 was determined by single crystal x-ray crystallog. and shown a cis configuration in a square planar structure. The chem. shifts for these complexes were observed by 31P{1H} NMR spectroscopy in the solution and they showed significant upfield shifts over 30 ppm relative to that of the free ligand. These upfield shifts indicate that the phosphorin ligand undergoes strong π-back donation from the central metal compared with general phosphine ligands and the difference of these upfield shifts between Pt and Pd is clearly appeared the degree of π-back donation from the central metal. The platinum and palladium complexes in solution also exhibit cis square planar configurations as shown by 31P{1H} and 13C{1H} NMR data.
