http://www.ichacha.net/phosphine.html 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. It was synthesized by Gottfried Märkl in 1966 by condensation of the corresponding pyrylium salt and phosphine or its equivalent ( … See more • Six-membered aromatic rings with one carbon replaced by an element from another group: borabenzene, silabenzene, germabenzene, stannabenzene, pyridine, phosphorine, See more Structural studies by electron diffraction reveal that phosphorine is a planar aromatic compound with 88% of aromaticity of that of benzene. Potentially relevant to its high aromaticity are the well matched electronegativities of phosphorus (2.1) and See more

WebApr 2, 2024 · The λ 5-phosphinine unit and EBDT moiety of 4 are almost orthogonal, suggesting that the π-π interaction between the EBDT and λ 5-phosphinine units are weakened. UV–vis absorption spectra of the 10 -4 M acetonitrile solution of neutral compounds 1 – 4 were measured at room temperature ( Fig. 2 ) and the results are … WebFeb 24, 2024 · The LUMO of a λ 5-phosphinine has a nodal plane through the heteroatom (a 2 symmetry) and is similar to the LUMO+1 orbital of a λ 3-phosphinine (Figure 6 and 7), as … WebOn the other hand, the oxidation can also be achieved by an exchange process from an aminophosphinine under acidic conditions. In particular, concentrated hydrochloric acid was used in the case of the λ 5-phosphinine 115 to synthesize the corresponding ester 116.Using the same conditions, the phosphinine diamine 117 is converted to the corresponding … devyani international share price expected
