Regiodirected Substitution of Paracyclophanedienes and Paracyclophanes through Tricarbonylchromium Complexation

4,7-dialkoxyparacyclophanes and the corresponding 1,9-dienes are shown to undergo selective complexation with Cr(CO)3L3-reagents on their less substituted benzene moiety.Lithiation/silylation of these complexes leads to arene- or bridge-substitution, respectively.An analogous behaviour is observed for the tricarbonylchromiumparacyclophane and its 1,9-diene.

Treatment of Dimethoxyparacyclophanes with Ammonium Cerium(IV) Nitrate
