72287-26-4, Name is [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), belongs to catalyst-palladium compound, is a common compound. Recommanded Product: [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II)In an article, once mentioned the new application about 72287-26-4.
Addition of isonicotinic acid NC5H4CO2H (or isonicH) to [Pt(dppf)(MeCN)2]2+2OTf– (dppf = l,1′-bis(diphenyl-phosphino)ferrocene, OTf = triflate) affords a mixture of the homometallic molecular square [Pt4(dppf)4(mu-O 2CC5H4N4]4+4OTf -, 1 and its precursor intermediate [Pt(dppf)(eta1- NC5H4CO2H)2]2+2OTf -, 2. The latter captures [Pd(dppf)(MeCN)2] 2+2OTf- to give a heterometallic square, [Pt 2Pd2(dppf)4(mu-O2CC 5H4N)4]4+4OTf-, 3. Slight skeletal modification of the ligand leads to different assemblies. This is illustrated by the addition of NC5H4CH2CO 2H·HCl to [Pt(dppf)(MeCN)2]2+2OTf – to give [PtCl(dppf)(NC5H4CH 2CO2H)]+OTf-, 4, which reacts with another equivalent of AgOTf to yield the dibridged complex [Pt 2(dppf)2(mu-NC5H4CH 2CO2)2]2+2OTf-, 5. All complexes, with the exception of 3, have been structurally characterized by single-crystal X-ray crystallography. Complexes 2 and 4 are potential precursors to further molecular topologies.
