Abstract
(Z)-Urocanic acid (cis-UA), unlike its (E) isomer (trans-UA), undergoe s photoisomerization in the presence of nitro blue tetrazolium (NBT2+) and sodium azide. Evidence is presented that the photoisomerization i nvolves the reversible addition of the azidyl radical to the double bo nd. (C) 1997 Elsevier Science Ltd.
