The use of a coordinated H 2 molecule as leaving group in order to generate an unsaturated reactive complex has proven to be an excellent entry to a new route for ethylene hydrogenation. 1 initially affords the 16e‐complex 2 , which immediately coordinates C 2 H 4 with formation of 3 , the first species of a catalytic cycle. With an excess of C 2 H 4 , the bisethylene complex 4 (as BF 4 ⊖salt) can be isolated as stable end product.
