Abstract
Optisch aktive Phosphinigsäurederivative 4 MePhPX (X = OR, SR) werden nicht erhalten durch Desulfurierung optisch aktiver Thiophosphinsäurederivate 3 (X = OR, SR) mit Natrium in flüssigem Ammoniak, Naphthalin-Natrium in THP, mit Kalium, mit Trimethylphosphin und Tributylphosphin und durch kathodische Spaltung. Die Inversions-barriere der Phosphinigsäurederivate liegt offenbar sehr niedrig. Chiral phosphinous acid derivatives 4 MePhPX (X = OR.SR) were not obtained following desulphurization of optically active thiophosphinic acid esters 3 (X = OR,SR), where sodium/liquid NH3, sodium-naphthalide (THF), potassium, trimethylphosphine, tributylphosphine, or cathodic fission were employed as agents. The barrier to inversion in phosphinous acid derivatives is obviously small.Keywords
