| dc.description.abstract | Photolysis of a dilute chloroform solution of 2-hydroxy 1.4 naphthoquinone with diffuse day light yielded 2-chloro-3- hydroxy-1,4-naphthoquinone (SB) and an unidentified compound (SA). Compound 58 was characterized by spectroscopic methods. Its photoformation from the materials used in the present study is unprecedented. The photochemical reaction of 2-hydroxy-1.4-naphthoquinone is carbon tetrachloride failed to yield to compound SB. On the other hand. the room temperature reaction of thionyl chloride or phosgene with the hydroxy quinone afforded a compound Y/hich. by comparative TLC. was identified as compound SO. The significance of these results is discussed, Photolysis of a dilute chloroform solution of 2-methoxy-1.4-naphthoquinone also gave a major reaction oroduct (SC) which has not been fully elucidated | en_US |
