4‐Alkyl(Aryl)‐λ5‐phosphorine; 1,4‐Dihydrophosphorin/λ5‐Phosphorin‐Umlagerung

Abstract: 4-Alkyl(Aryl)-i5-phosphorins; 1,4-Dihydrophosphorin/is-Phosphorin RearrangementThe 1 -R'-4-R-4-methoxy-l,4-dihydrophosphorins 11 -17, the 'H-and I3C-NMR spectra and stereochemistry of which are discussed, are formed by reaction of (1 Z , 42)-1,5-dilithio-3-R-3-methoxy-1,4-pentadienes 9 with R'PCI, [R' = aryl, alkyl, N(C2H5),, OC4H,, SC,H,] at -78°C. -Addition of catalytic amounts of acid causes rearrangement of the 1,4-dihydrophosphorins and yields the 1 -R'-l -methoxy-4-R-h5-phosphorins 23 -29 which represent… Show more
