WebJan 21, 2024 · Phosphinines, as aromatic heterocycles, usually engage in coordination as η 1-P σ-complexes or η 6-phosphinine π-complexes.The μ 2-P bridging coordination mode is rarely observed.With the aim to study the effect of different electronic configurations of phosphinines on the coordination modes, a series of anionic phosphinin-2-olates and … WebNov 4, 2024 · Their reaction with CuBr⋅S(CH 3) 2 affords Cu I complexes with the first example of a neutral phosphinine acting as a rare bridging μ 2-P-4e donor-ligand between two Cu I centers. Our experimental and theoretical investigations show that 2-aminophosphinines are missing links in the series of known 2-donor-functionalized …
A Phosphinine 2-Carboxaldehyde Organic Letters
WebSep 28, 2012 · During my PhD under the supervision of Pascal Le Floch, I studied the chemistry of the phosphinine, the phosphorus equivalent of the pyridine. This highly electron accepting ligand was used to study one electron bonding interactions, to make unprecedented rhodium and palladium complexes, and to stabilized gold nanoparticles. WebAccess to homoleptic phosphinine-based coordination compounds of d 6 metals has so far remained elusive. We report here on the preparation and full characterization of the first homoleptic phosphinine–iridium (III) complex, obtained by C–H activation of 2,4,6-triphenylphosphinine with [Ir (acac) 3 ]. church of the messiah canton ga
Synthesis and Photophysical Properties of λ5
WebFeb 24, 2024 · A new series of 2,4,6-triaryl-λ 5 -phosphinines have been synthesized that contain different substituents both on the carbon backbone and the phosphorus atom of the six-membered heterocycle. Their optical and redox properties were studied in detail, supported by in-depth theoretical calculations. WebRhodium complexes represent some of the most widely propagated industrial homogeneous catalysts, and classic examples include olefin hydrogenation by Wilkinson’s catalyst [RhCl(PPh 3) 3], the carbonylation of methanol to produce acetic acid by using the catalyst precursor [Rh(CO) 2 I 2] – in the Monsanto process, and the hydroformylation of alkenes … Phosphorine (IUPAC name: phosphinine) is a heavier element analog of pyridine, containing a phosphorus atom instead of an aza- moiety. It is also called phosphabenzene and belongs to the phosphaalkene class. It is a colorless liquid that is mainly of interest in research. Phosphorine is an air-sensitive … See more The first phosphorine to be isolated is 2,4,6-triphenylphosphorine.
