Abstract
Optically pure 2-benzylsuccinic acid is obtained by optical resolution of the racemates with the chiral host 1-phenylethylamine. The structure of the salt complex between (S)-2-benzylsuccinic acid and (R)-1-phenylethylamine was first elucidated by X-ray analysis, indicating that the hydrogen bonds are formed between the acetate anions and the protonated amino group. The intermolecular hydrogen bond links the salt complex into a quasi-two-dimentional net-like structure.
