Ozonolysis of 1,2‐Dichloroacenaphthylene

Abstract

yellowish fluorescence were obtained after treatment of the natural material with M n 0 2 in acetic acid solution; they were regarded as possible unconjugated pteridines. However, since none of these products could be identified by chromatographic or spectroscopic methods as one of the natural pterins we have re-investigated them. First of all, the component showing the greatest migration on chromatography on cellulose with n-propanol/l% ammonia (2/1) (R,= 0.48) was
