Application In Synthesis of Diiodo(1,5-cyclooctadiene)platinum(II). The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Diiodo(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12I2Pt, CAS is 12266-72-7, about Formation of metallamacrocycles from palladium(II), platinum(II) and copper(I) complexes and the ditopic ligands [{p-(Ph2PO)C6H4}2CMe2], [{2-Ph2PO-3,5-(Me3C)2C6H2}2S], [{p-[(C10H6O)2PO]C6H4}2CMe2].

The new ligands bis(phosphinito) [{2-Ph2PO-3,5-(Me3C)2C6H2}2S] (4) and chiral bis(phosphite) [{p-[(C10H6O)2PO]C6H4}2CMe2] (5) were synthesized and their reactions with Pd(II), Pt(II), Cu(I) substrates were studied. [{P-(Ph2PO)C6H4}2CMe2] (3), previously reported by the authors, was also used in the same reactions. Ligands 3 and 5 formed 28-membered metallamacrocycles while ligand 4 afforded the analogous compound only in the reaction with the Cu(I) substrate. In the reaction of 3 with [Pd(PhCN)2Cl2] the metallamacrocycle [PdCl2(μ-3)]2 (6) or the oligomer [Pd2Cl4(μ-3)]n (7) were formed, depending on the molar ratio used. The reaction of 3 with [Pd(η3-C3H5)Cl]2 afforded {[Pd(η3-C3H5)Cl]2(μ-3)} (8). The allylpalladium macrocycle [Pd(η3-C3H5)(μ-3)]2[OTf]2 (9) was obtained by treating a solution of 8 in THF with AgCF3SO3. The reactions of 3 with [Pt(COD)I2] or [Cu(NCCH3)4]BF4 gave metallamacrocycles [PtI2(μ-3)]2 (10) and [Cu2(μ-3)2][BF4]2·2MeCN (11), resp. The structure of 10 was also elucidated by x-ray anal. Reactions of 4 with Pd(II) and Pt(II) complexes afforded a mixture of two very different compounds in almost an equimolar ratio. An x-ray anal. established that one is a mononuclear compound, formed by modification of the ligand 4, containing a P,S-chelate, [PdCl2{[2-Ph2PO-3,5(Me3C)2C6H2][3,5-(Me3C)2C6H2OH]S}] (12). The reaction between [Cu(NCCH3)4]BF4 and 4 afforded the ionic metallamacrocycle [Cu(μ-4)][BF4]2·2MeCN (14). In compound 10, the size of the central cavity formed by the bridging ligand 3 was determined
After consulting a lot of data, we found that this compound(12266-72-7)Application In Synthesis of Diiodo(1,5-cyclooctadiene)platinum(II) can be used in many types of reactions. And in most cases, this compound has more advantages.
