Yttrium-Alkyl Complexes Supported by a Ferrocene-Based Phosphinimine Ligand
No full textThe
synthesis and characterization of two yttrium alkyl complexes
supported by a bisphosphinimine ferrocene ligand, <b>NP</b><sup><b>fc</b></sup> (1,1′-di(2,4-di-<i>tert</i>-butyl-6-diphenylphosphiniminophenoxy)ferrocene), were accomplished.
Although <b>(NP</b><sup><b>fc</b></sup><b>)Y(CH</b><sub><b>2</b></sub><b>Ph)</b> and <b>(NP</b><sup><b>fc</b></sup>)<b>Y(CH</b><sub><b>2</b></sub><b>SiMe</b><sub><b>3</b></sub><b>)</b> could be structurally
characterized, these compounds are thermally sensitive and decompose
at ambient temperature within hours. Their characterization was accomplished
by NMR spectroscopy, electrochemical measurements, and elemental analysis.
Reactivity studies were also carried out; however, the lack of prolonged
thermal stability at ambient temperature of these molecules led to
decomposition before a clean transformation to reaction products could
be observed
