Anionic chromium alkoxide

Reaction of haloafene chromium tricarboriyl complexes [Cr(CO)3ArX] with alkoxide anions... 

As with the analogous chromium complexes (420), anions (R ) such as hydride, cyanide, alkoxide, etc., add to cyclohexa- or cyclohepta-dienyliron complexes to form the sub.stituted species of structure (107) (299). Reduction of the cycloheptadienyliron cation with zinc dust... 

Complexation of organic compounds with organometallic moieties can modify substantially their properties, thus allowing the desired transformations to proceed. A variety of such transformations with organometallic complexes or organometallic compounds can be executed under PTC conditions. For instance, nucleophilic substitution of the halogen in halobenzenes usually requires harsh conditions. Conversion of these arenes into chromium tricarbonyl complexes facilitates these reactions. PTC is a method of choice for the execution of such a process with inorganic anions, alkoxides, etc.
