A zwitterionic triphosphenium compound as a tunable multifunctional donor

15 December, 2015 - 05:17

Dalton Trans., 2016, Advance Article
DOI: 10.1039/C5DT03915K, PaperStephanie C. Kosnik, Charles L. B. Macdonald
We present a zwitterionic triphosphenium molecule which features dicoordinate, tricoordinate and tetracoordinate phosphorus centers in addition to a cyclopentadienyl moiety. Crystallographic, computational, electrochemical and spectroscopic data illustrate and rationalize the reactivity of this molecule as a multifunctional ligand for both transition metals and main group acceptors and suggest how the donor properties may be tuned.
