Laevulic acid

The 13C NMR spectrum of phthalic dichloride shows additional signals for a five-membered cyclic pseudo halide, characterized by an sp3 carbon shift of 104 ppm. This shift value is also observed for laevulic acid chloride, which exists in the cyclic form only. Similarly, phthalaldehyde acid (o-formylbenzoic acid) turns out to be hydroxyphthalide, as indicated by a hemiacetal carbon shift of 98.4 ppm. [Pg.232]
