Electric Literature of 12150-46-8. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene
PdCl[PPh2CH2CH2CH-(cyclic)CH2CH2PPh2] as a precursor to homo- and hetero-metallic species directed by ESMS (electrospray ionisation mass spectrometry)
The cyclometallated Pd compound PdCl[PPh2CH2CH2CH-(cyclic)CH2CH2PPh2]1, obtained from PdCl2(Ph2P(CH2)5PPh2) in refluxing DMF (N,N-dimethylformamide), was characterized by NMR and X-ray single-crystal diffraction analysis. The cyclometallation of MCl2(Ph2P(CH2)5PPh2) (M = Pd, Pt) to give 1 and its Pt(II) analogue was probed using electrospray ionisation mass spectrometry (ESMS). The reactivity of 1 towards neutral ligands such asphosphines and pyridines as well as basic metal complexes such as pyrid ine-thiolate compounds of Au(I), Hg(II) and Pt(II) in solution was also investigated. The results showed that the chloride trans to the Pd-C bond is susceptible to ligand replacement. A number of entry metalloligandswas examined in an attempt to establish a route to cyclometallated aggr egates and clusters.
