Based on neighbouring group participation, we have proposed a bi-bridge reaction mechanism, i.e. in the path of the reaction, there is a bi-bridged structure with two bridging atoms across a single carbonus-cacbon bond. We have studied it by ab initio molecular orbital calculation. And all the geometries of the bi-bridge structines studied by us are transition states of the bi-bridge reaction. The theoretical data of structures, energies, and charge distribution give good information about such kind of reactions.

Key words: Bi-bridge reaction mechansim, Ab initio calculation, Neighbouring group participation
