The presence of silver perchlorate changed the products in the reaction of benzyne with substituted benzene (anisole, toluene, chlorobenzene or methyl benzoate) to increase biphenyl and/or benzylidyne trifluoride derivatives by the sacrifice of benzobicyclo[2.2.2]octatriene derivatives. In the case of toluene, <I>o</I>-methylbiphenyl (<B>15</B>) and 6-methylbenzocyclooctene (<B>14</B>) were considered to be formed <I>via</I> common intermediate. These results were well explained by an assumption of benzyne–silver cation complex. From competition experiments, it was concluded that benzyne-silver cation complex assumed here had a stronger electrophilicity than benzyne itself.
