Formation of α-hydroxyketones via irregular Wittig reaction

Αddition reactions of (1-methoxyalkyl)triphenylphosphonium ylides, derived from the corresponding Wittig salts and n-BuLi, to aldehydes were investigated. It was revealed that the betaine LiX complexes, the primary adducts, were converted to α-hydroxyketones, prior to the formation of oxaphosphetanes, by addition of aqueous NH4Cl at low temperature.

STUDY OF (1-ALKOXYETHYL)DIPHENYLPHOSPHINE OXIDES. I. SYNTHESES AND STRUCTURAL ANALYSES OF PHENYLETHOXY, METHOXY AND ISOPENTYLOXY DERIVATIVES

1-Phenylethoxy- (9), 1-methoxy- (10), 1-isopentyloxy- (11) and 1-dodecyloxy- (12) ethyldiphenylphosphine oxides, key intermediates in the stereospecific syntheses of vinyl ethers, have been synthesised and characterised by 1H NMR and 13C NMR, IR and mass spectra.The crystal structures of compounds 9-11 have been determined by X-ray analysis.In the solid state only monomeric molecules have been found, despite the evidence of dimer formation in the mass spectra.The three molecules are in different conformations and a comparison with the geometry of similar compounds, retrieved from the Cambridge Structural Database, indicates a dominant contribution of the steric factors in dictating the different conformations.
