1 having two aromatic groups at C-1 position and one methyl group at the C-2 position of cyclopropyl ring, the reaction with bromine at low temperature (−100 °C) produces the brominated indene derivatives 2 and conjugated triene derivatives 3 in high yields in dichloromethane and ether within 10 min, respectively. This drastic solvent effect has been discussed on the basis of previous investigation

Novel dimeric allylpalladium(II) complexes have been successfully synthesized from the transition metal PdCl2-promoted ring-opening reactions of VDCPs 1 in good yields. These dimeric allylpalladium(II) complexes have been characterized by X-ray crystal structure diffraction.
