Title: | From a trinuclear platinum(III) phosphido derivative to a platinum(II) cluster: Formation of a P−C bond |
Authors: | Forniés, Juan CSIC; Fortuño, Consuelo CSIC ORCID; Ibáñez, Susana CSIC ORCID; Martín, Antonio CSIC ORCID | Issue Date: | Apr-2006 | Publisher: | American Chemical Society | Citation: | Inorganic Chemistry 45(12): 4850-4858 (2006) | Abstract: | Reaction of the trinuclear PtIII−PtIII−PtII [(C6F5)2PtIII(μ-PPh2)2PtIII(μ-PPh2)2Pt(C6F5)2] (2) derivative with NBu4Br or NBu4I results in the formation of the trinuclear PtII complexes [NBu4][(PPh2C6F5)(C6F5)Pt(μ-PPh2)(μ-X)Pt(μ-PPh2)2Pt(C6F5)2] [X = I (3), Br (4)] through an intramolecular PPh2/C6F5 reductive coupling and the formation of the phosphine PPh2C6F5. The trinuclear PtII complex [(PPh2C6F5)(C6F5)Pt(μ-PPh2)Pt(μ-PPh2)2Pt(C6F5)2] (5), which displays two Pt−Pt bonds, can be obtained either by halide abstraction in 4 or by refluxing of 2 in CH2Cl2. This latter process also implies an intramolecular PPh2/C6F5 reductive coupling. Treatment of complex 5 with several ligands (Br-, H-, and CO) results in the incorporation of the ligand to the cluster and elimination of one (X = H-) or both (X = Br-, CO) Pt−Pt bonds, forming the trinuclear complexes [NBu4][(PPh2C6F5)(C6F5)Pt(μ-PPh2)(μ-X)Pt(μ-PPh2)2Pt(C6F5)2] [X = Br (6), H (7)] or [(PPh2C6F5)(C6F5)Pt(μ-PPh2)2Pt(μ-PPh2)(CO)Pt(C6F5)2(CO)] (8). The structures of the complexes have been established on the basis of 1H, 19F, and 31P NMR data, and the X-ray structures of the complexes 2, 3, 5, and 7 have been established. The chemical relationship between the different complexes has also been studied. | Description: | 9 pages, 5 tables, 3 figures, 3 schemes.-- Supporting Information Available: http://pubs.acs.org. | Publisher version (URL): | http://dx.doi.org/10.1021/ic0602695 | URI: | http://hdl.handle.net/10261/19776 | DOI: | 10.1021/ic0602695 | ISSN: | 0020-1669 |
