Abstract
Cycloaddition reaction of 4-phenyl-1,2,4-triazoline-3,5-dione(PTAD) to bicyclo[5.3.0]deca-1 (7),2,4-trien-10-one (3) was reinvestigated. In various conditions, the reaction afforded solely 1:1 cycloadduct as re ported. The structure of this adduct, previously thought to be a forma l [6+2] adduct, was revised. This adduct is now thought to be a cycloh eptatriene-derived [4+2] adduct on the basis of extensive H-1- and C-1 3-NMR studies.
