The structures, energies, elec. charge distributions and other relevant data of all isomers of dichlorocarbonyl ylides formed from the reaction between dichlorocarbene and benzaldehyde were obtained by the SCF-MNDO method. According to the computation results, the different chem. behaviors of the isomers was studied and the mechanism of the reaction between dihalocarbene and benzaldehyde was discussed.
