摘要

Oxidative addition of aryl iodides ArI (Ar=(a) C6H5,(b) C6H4CF3,(c) C6H3 (CF3) 2,(d) C6H4CH3,(e) C6H4OCH3), to the PCP-type complex Rh (PPh3)[CH2C6H (CH3) 2 (CH2PPh2) 2](1), yields the complexes Rh (Ar)[CH2C6H (CH3) 2 (CH2PPh2) 2](I)(2a-e). Compounds 2a-e undergo intramolecular methylene transfer from the bis-chelating ligand to the incoming aryl under mild conditions (room temperature) giving Rh (CH2Ar)[C6H (CH3) ...
