Abstract
Photocyclization of the substituted 2-(naphth-1-yl)-3-(thien-2-yl)prop enoic acid (3) in the presence of iodine and air in a benzene-cyclohex ane mixture afforded a separable mixture of three compounds, phenanthr o[2,1-b]thiophene-10-carboxylic acid (4), phenanthro[2,1-b]thiothene ( 5), and naphtho[1,8-cde]-thieno[3,2-g][2]benzopyran (6).
