PhC(O)C(O)Ph + 2 H 2 → PhCH(OH)CH(OH)Ph (R,R isomer) This transformation is an example of desymmetrization , the symmetric molecule benzil is converted to the dissymmetric product. DPEN is a key ingredients of Ryōji Noyori 's 2nd generation ruthenium -based chiral hydration catalyst, for which he earned the Nobel Prize in Chemistry in 2001.
Many syntheses have been developed. One popular route entails reduction of benzoin using zinc amalgam. [6]C 6 H 5 –CH(OH)–C(=O)–C 6 H 5, trans-C 6 H 5 –CH=CH–C 6 H 5. Both isomers of stilbene can be produced by decarboxylation of α-phenylcinnamic acid, trans-stilbene being produced from the (Z)-isomer of the acid.
