Abstract: | It was inferred from the collisional activation spectra that CO loss from [M – CH3]+ ions generated from o-,m- and p-cyanoanisole yields a common ion, presumably the cyanocyclopentadienyl cation. A similar product ion is found to be generated in the three dimethoxybenzene isomers. In case of o-dimethoxybenzene loss of CO was also found to occur via an important additional route, which leads to the formation of protonated phenol. |
