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.SDS of cas: 12266-72-7.Bennett, Martin A.; Jin, Hong; Willis, Anthony C. published the article 《Preparation and x-ray structure of a platinum(II) hydroxycarbonyl, Pt(CO2H){C6H3(CH2PPh2)2-2,6}, containing a trans-spanning, tridentate P,C,P-ligand》 about this compound( cas:12266-72-7 ) in Journal of Organometallic Chemistry. Keywords: bisphosphinomethylbenzene cyclometalation platinum; crystal structure platinum cyclometalated diphosphine hydroxycarbonyl; mol structure platinum diphosphine hydroxycarbonyl. Let’s learn more about this compound (cas:12266-72-7).
The ligand 1,3-{bis(diphenylphosphino)methyl}benzene, 1,3-C6H4(CH2PPh2)2 (3a) undergoes cyclometalation on heating in 2-methoxyethanol either with PtCl(CH3)(COD) or, in the presence of 2-methylaminoethanol, with PtCl2(COD) to give PtCl{C6H3(CH2PPh2)2-2,6} [I; R = Ph, X = Cl (6)]. In this complex, the tridentate anionic ligand C6H3(CH2PPh2)2-2,6 (2a) is attached to platinum via a σ-bonded carbon atom and mutually trans-phosphorus atoms. Successive treatment of 6 with AgBF4 and KOH gives the hydroxo-complex I (R = Ph, X = OH), which reacts with CO to give the corresponding hydroxycarbonyl I [X = CO2H (12)]. The structure of 12·1.5C6H6 was determined by x-ray diffraction methods and shown to consist of a dimer in which two planar trans-Pt(CO2H)(2a) units are joined by hydrogen-bonded carboxylate groups. The hydrogen-bonded O…O distance [2.750(4)Å] is significantly larger than that in trans-Pt(CO2H)(C6H5)(PEt3)2 [2.695(8)Å], which may be related to the greater tendency of 2a to form a monomer in dichloromethane.
This literature about this compound(12266-72-7)SDS of cas: 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.
