Photolysis of 2-diazo[1-13C]naphthalen-1(2H)-one
Abstract
Oxiren participation in the Wolff rearrange-ment of 2-diazo[1-13C]naphthalen-1(2H)-one (IV) is investigated; photolysis of (IV) yields indene-1-carb-oxylic acid containing all the label in the carboxy-group, excluding intermediate formation of an oxiren.
