摘要
The photochemical reactions of 4-methyl-2-quinolinecarbonitrile (MQCN) with the enantiomers of 2-phenylpropionic acid (PPA) has been studied by CIDNP technique. The problem of chemical behavior discrimination of the enantiomers of PPA proposed by Hata(1) was examined. In contrast to the proposal of Hata, both (R) and (S) forms of PPA are shown to have radical intermediates in their reaction with MQCN.
