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
