In just four steps from ferrocene , macrocyclic ferrocenyl bispalladacyles have been synthesized by using a diastereoselective biscyclopalladation reaction as the key step. The complexes not only possess a fascinating structure but are also the first highly active catalysts for the title reaction (see scheme), requiring as little as 0.1 mol % of catalyst for most of the substrates. Ts=toluene‐4‐sulfonyl.
