Sažetak
Pummerer's ketone (I) undergoes [4+2] cycloaddition to furan (II) and [2+2] cycloaddition to alkenes (IV) and (VI) via a comon intermediate, namely the short-lived twisted triplet excited state of (I). The structure of the Products (V), (VIII) (both space groups P21/c), (VIIa) (space group P21/n) and (VIIb) (space group C2/c) is confirmed by x-ray analysis.
