New "Cp2Zr"-Mediated Ring Transformations of 2-Vinylheterocycles to Carbocycles. -2-Vinylheterocycles undergo a novel ring transformation mediated by Cp2ZrCl2 via an intramolecular allylation of Z-allylic zirconocene species. The epoxide or aziridine intermediates thus obtained rearrange mainly to c
