The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Diiodo(1,5-cyclooctadiene)platinum(II)( cas:12266-72-7 ) is researched.Application of 12266-72-7.Moldovan, Natalia; Loennecke, Peter; Silaghi-Dumitrescu, Ioan; Silaghi-Dumitrescu, Luminita; Hey-Hawkins, Evamarie published the article 《Palladium(II) and Platinum(II) Complexes with Heteroditopic 10-(Aryl)phenoxarsine (Aryl = 2-C6H4OR, R = H, Me, Pri) Ligands: Solvent-Oriented Crystallization of cis Isomers》 about this compound( cas:12266-72-7 ) in Inorganic Chemistry. Keywords: phenoxarsine aryl preparation complexation platinum palladium; palladium arylphenoxarsine complex preparation; platinum arylphenoxarsine complex preparation; crystal structure palladium platinum arylphenoxarsine complex; energy optimized geometry palladium platinum arylphenoxarsine complex. Let’s learn more about this compound (cas:12266-72-7).
The synthesis and characterization of 10-(o-alkoxyphenyl)phenoxarsines 2-ROC6H4As(C6H4)2O (R = H, Me, and Pri, As(C6H4)2O = phenoxarsine) and their Pt(II) and Pd(II) complexes cis-[PtCl2{2-PriOC6H4As(C6H4)2O-κAs}2] (1), trans-[PdCl2{2-PriOC6H4As(C6H4)2O-κAs}2] (2), cis-[PtCl2{2-HOC6H4As(C6H4)2O-κAs}2] (3), cis-[PdCl2{2-HOC6H4As(C6H4)2O-κAs}2] (4), cis-[PtI2{2-MeOC6H4As(C6H4)2O-κAs}2] (5), and trans-[PdCl2{2-MeOC6H4As(C6H4)2O-κAs}2] (6) are reported. The chelate complex cis-[Pt{2-OC6H4As(C6H4)2O-κAs,O}2] (7) is also described. The mol. structures of 1-4 and 7 were determined The short As···O intramol. interaction found in complexes 1-4 in the solid state was also verified by calculations at the B3LYP/LANL2DZ level for complex 2 and for 10-(o-isopropoxyphenyl)phenoxarsine in the gas phase, and probably the interaction is a characteristic of the ligand rather than a packing effect. Calculations at the B3LYP/LANL2DZ and Oniom(B3LYP/LANL2DZ:uff) levels for complexes 1-4 showed that the solvent plays a crucial role in the crystallization (through geometry constraints) of the kinetically stable cis isomers.
This literature about this compound(12266-72-7)Application of 12266-72-7has given us a lot of inspiration, and I hope that the research on this compound(Diiodo(1,5-cyclooctadiene)platinum(II)) can be further advanced. Maybe we can get more compounds in a similar way.
