The reaction of the title compound (I) with mercuric halide in an aprotic and in a protic solvent afforded the fulvene derivative (VII) and the dihydrofuran derivative (VIII or IX) respectively. Both the cross-reactions (bromo-analog of I (Ia)+HgCl2, chloro-analog of I (Ib)+HgBr2) in an aprotic solvent afforded the chloro-fulvene derivative (VIIb). However, when the above reactions were carried out
