New cationic, square‐planar, ethene complexes [(Rbpa)Rh I (C 2 H 4 )] + [ 2 a ] + –[ 2 c ] + (Rbpa= N ‐alkyl‐ N,N ‐di(2‐pyridylmethyl)amine; [ 2 a ] + : alkyl=R=Me; [ 2 b ] + : R= Bu; [ 2 c ] + : R= Bz) have been selectively oxygenated in acetonitrile by aqueous hydrogen peroxide to 2‐rhoda( III )oxetanes with a labile acetonitrile ligand, [(Rbpa)Rh III ( κ 2 ‐ C,O‐ CH 2 CH 2 O−)(MeCN)] + , [ 3 a ] + –[ 3 c ] + . The rate of elimination of acetaldehyde from [(Rbpa)Rh III ( κ 2 ‐ C,O ‐CH 2 CH 2 O−)(MeCN)] + increases in the order R=Me
