Phosphaalkenes with inverse electron density: Electrochemistry, eectron pramagnetic rsonance spectra, and density functional theory calculations of aminophosphaalkene derivatives

Cyclic voltammetry of Mes* P=C (NMe2) 2 and Mes*P=C (CH3) NMe2 (2) shows that, in solution in DME, these compounds are reversibly oxidized at 395 and 553 mV, respectively. The electronic behavior of inversely polarized phosphaalkenes 1 and 2 is found to be unexpectedly rich.
