Johnson, David K.; Rukachaisirikul, Thitima; Sun, Yan; Taylor, Nicholas J.; Canty, Allan J.; Carty, Arthur J. published the article 《Coupling of acetylenes held proximate to a metal: alkyne-alkyne interactions in cis-phosphinoacetylene complexes, including structural characterization of the unsymmetrical diphosphine 1-phenyl-2,3-bis(diphenylphoshino)naphthalene and three platinum(II) complexes of Ph2PCCPh》. Keywords: acetylene platinum coordination coupling reaction; diphosphinonaphthalene formation crystal structure; naphthalene diphosphinophenyl formation structure; platinum phosphinoacetylene derivative complex structure reaction; crystal structure diphosphinonaphthalene platinum phosphinoacetylene complex.They researched the compound: Diiodo(1,5-cyclooctadiene)platinum(II)( cas:12266-72-7 ).Synthetic Route of C8H12I2Pt. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:12266-72-7) here.
Cis-PtX(Z)(Ph2PCCPh)2 [X = Z = Cl, I, CF3, C6F5, Me; X(Z) = o-C6H4O2, Me(Cl)] were synthesized, and for all of the complexes except for di-Me complex, intramol. coupling of the phosphinoacetylene ligands occurs on heating to form cis-PtX(Z){o-C16H10(PPh2)2]. A mixture of the 2 possible structural isomers is formed for cis-PtMe(Cl){o-C16H10(PPh2)2}. Cis-PtMe2{o-C16H10(PPh2)2} was obtained by reaction of the dichloro analog with MeLi. Unsym. 1-phenyl-2,3-bis(diphenylphosphino)naphthalene [o-C16H10(PPh2)2], produced as a coordinated ligand via these intramol. coupling reactions, was isolated in moderate yield from the dichloro complex and its structure determined by x-ray diffraction. Crystals of o-C16H10(PPh2)2 are triclinic, space group P1, Z = 2, R = 0.058, Rw = 0.070. Structure determinations of cis-PtCl2(Ph2PCCPh)2.2MeCN, cis-PtMe(Cl)(Ph2PCCPh)2.0.5CH2Cl2, and cis-PtMe2(Ph2PCCPh)2 were carried out to evaluate interligand interactions in the complexes. Crystal data: cis-PtCl2(Ph2PCCPh)2.2MeCN, monoclinic, space group P21/c, Z = 4, R = 0.031, Rw = 0.035; cis-PtMe(Cl)(Ph2PCCPh)2.0.5CH2Cl2, orthorhombic, space group Pbca, Z = 8, R = 0.039, Rw = 0.044; cis-PtMe2(Ph2PCCPh)2, orthorhombic, space group Pbca, Z = 8, R = 0.037, Rw = 0.042. Factors affecting the occurrence of intramol. coupling are assessed, together with a comparison of this reaction with related reactions of organic diacetylenes. Cis-PtMe(Cl)(Ph2PCCPh)2 reacts with Ph2PH to form a mixture of the 2 structural isomers of cis-PtMe(Cl){Ph2PCH:C(Ph)PPh2}.
From this literature《Coupling of acetylenes held proximate to a metal: alkyne-alkyne interactions in cis-phosphinoacetylene complexes, including structural characterization of the unsymmetrical diphosphine 1-phenyl-2,3-bis(diphenylphoshino)naphthalene and three platinum(II) complexes of Ph2PCCPh》,we know some information about this compound(12266-72-7)Synthetic Route of C8H12I2Pt, but this is not all information, there are many literatures related to this compound(12266-72-7).
