Reductive cleavage of the halogen-phosphorus and sulfur-phosphorus bonds with alkali metals
Stankiewicz, Marek,Nycz, Jacek,Rachon, Janusz
, p. 330 - 339 (2007/10/03)
The reduction of thiophosphorus acid chlorides with alkali metals (Na, K) in liq. NH3/THF solution, potassium anthracenide, and potassium napththalenide was investigated. It was found that these types of phosphorus compounds easily undergo reduction to 〉P-S- anions. It was also demonstrated that 〉P-O- and 〉P-S- anions as well very efficiently undergo sulfurization with elementary sulfur in liquid ammonia to yield 〉P(O)S- and 〉P(S)S- anions, respectively.
A new, stereoselective interconversion of phosphinothio-phosphinoseleno compounds, reduction of phosphinoseleno derivatives and retro pishchimuka rearrangement based on methylthio- and methylselenophosphonium salts chemistry
Omelanczuk, Jan
, p. 8887 - 8898 (2007/10/02)
The interconversion of thiono- into seleno compounds was found to proceed with retention of the configuration at phosphorus and the mechanistic course of this process has been proposed. The isomerization reaction of phosphinothiolates into thiono-isomers via the phosphonium salts has been developed and considered as the "retro Pishchimuka" rearrangement.
Reaction of Thiolo and Seleno Esters of Phosphorus Acids with Halogens. 1. Stereochemical and 31P NMR Studies of Reaction of S-Methyl tert-Butylphenylphosphinothiolate with Elemental Chlorine and Sulfuryl Chloride

Reaction of S-methyl tert-butylphenylphosphinothiolate (4) with elemental chlorine and sulfuryl chloride involves chlorolysis of the P-S bond and formation of the tert-butylphenylphosphinochloridate 5.It is demonstrated here that the stereoselectivity of
The Proton Magnetic Resonance Spectra of Chiral Phosphinate Esters. Chemical Shift Non-equivalence of Enantiomers induced by Optically Active Phosphinothioic Acids
Harger, Martin J. P.
, p. 1505 - 1511 (2007/10/02)
The 1H n.m.r. spectrum of racemic methyl methylphenylphosphinate recorded in CCl4 solution in the presence of 1 mol. equiv. of (+)-(R)-phenyl-t-butylphosphinothioic acid or (-)-(S)-methylphenylphosphinothioic acid contains well separated P-m
