Romanov, S. R. published the artcileCarboxylate Phosphabetaines Containing Chiral Carbon Atom: Synthesis and NMR Spectroscopy Data, Recommanded Product: (E)-3-(3-Nitrophenyl)acrylic acid, the publication is Russian Journal of General Chemistry (2021), 91(7), 1333-1341, database is CAplus.
Abstract: The nucleophilic addition reactions of tertiary phosphines and unsaturated carboxylic acids have led to the formation of mono- and dicarboxylate phosphabetaines containing an asym. carbon atom. The data of 1D and 2D NMR spectroscopy have revealed the presence of diastereotopic geminal protons of the CH2 group adjacent to the chiral center in the obtained compounds The values of spin-spin coupling constants of the vicinal hydrogen atoms have coincided with the dihedral angles values (X-ray diffraction anal. data).
