Abstract

Not CO elimination/addition with “ring slippage” but rather a concerted straightening and bending of the two C₅H₅ rings in 2 is responsible for ring interchange. The reaction was studied by high-pressure ¹H and ¹³C NMR measurements of 1/CO. The activation barrier for the ring interchange is 13.5 ± 1 kcal mol⁻¹. An analysis of the electronic situation in 2 explains this unusual behavior.
