Substituent effects on regioselectivity in the photorearrangement of a few naphthobarrelenes

The photorearrangement of a few 9,10-disubstituted-naphthobarrelenes to the corresponding naphthosemibullvalenes has been examined. It was observed that the regioselectivity in these photoisomerizations depends on the relative stabilities of the diradical intermediates. AM1 semi-empirical calculations are in support of this view. Thermal transformation of the naphthosemibullvalenes gave the corresponding water added naphthopentalenofurans, in nearly quantitative yields. (C) 2000 Elsevier Science Ltd.
