PHOTOCHEMICAL-REACTION OF 4-METHYL-2-QUINOLINECARBONITRILE WITH OPTICALLY-ACTIVE (S)-2-PHENYLPROPIONIC ACID OR (R)-2-PHENYLPROPIONIC ACID -THE MAGNETIC-FIELD AND SOLVENT EFFECTS AND CHIRAL-SYMMETRY BREAKING -COMMENT

R-(-)- and S-(+)-2-phenylpropionic acids exhibit equivalent reactivity toward the excited state of 4-methyl-2-quinoline-carbonitrile carboni trile in acetonitrile. No significant magnetic field effects were obse rved upon the relative quantum yield for photochemical reactions betwe en the quinolinecarbonitrile with the optically active 2-phenylpropion ic acids in benzene. No unusual phenomena were observed under well con trolled conditions with sufficient repetitions.
