[摘要]:An aryl Grignard reagent in the presence of mesityl iodide converts an allyllc C-H bond of a cycloalkene or an allylbenzene derivative into a C-C bond in the presence of a catalytic amount of Fe(acac)(3) and a diphosphine ligand at 0 degrees C. The stereo- and regioselectivity of the reaction, together with deuterium labeling experiments, suggest that C-H bond activation Is the slow step In the catalytic cycle preceding the formation of an allyliron intermediate. |
