Diethyl (Z)-1H-F-1-alkene-1-phosphonates were synthesized in good yields by the treatment of diethyl (Z)-1-[(diethoxyphosphinyl) oxy]-F-1-alkene-1-phosphonates, prepared from F- alkanoic acid chlorides and triethyl phosphite, with butylcopper (I) reagent in tetrahydrofuran-tetramethylethylenediamine at −78 °C.
NEW PALLADIUM-CATALYZED ADDITION OF CYANOTRIMETHYLSILANE TO<i>F</i>-ALKYLATED 1-AZA-1,3-DIENES. A CONVENIENT ROUTE TO β,γ-UNSATURATED α-<i>F</i>-ALKYL-α-AMINO ACID PRECURSORS
2-F-Alkylated 1-aza-1,3-dienes, easily prepared from 1H-F-1-alkenephosphonates, smoothly underwent the addition of cyanotrimethylsilane in the presence of a catalytic amount of palladium(II) acetate or chloride to give β,γ-unsaturated α-F-alkyl-α-amino nitriles and/or γ-F-alkyl-γ-amino nitriles in good yields.
