Synthesis of square‐planar carbene complexes was the goal , but a novel catalytic olefin synthesis was the result. A mixture of diphenyldiazomethane and its derivatives 1 with ethene, propene, or styrene provided, in the presence of catalytic amounts of [{RhCl(C 2 H 4 ) 2 } 2 ], a good yield of the olefins 2 , with turnover numbers as high as 500 (R H, Me, Ph; R′ H, Me, Cl, etc.).
