A crepuscular catalyst : Alkene migration catalyzed by [(RCN) 2 PdCl 2 ] complexes proceeds through an in situ generated Pd‐H species. Addition of a 1,5‐diene inhibits migration and allows the slower background catalysis of E/Z interconversion to be studied. Experimental and computational results suggest this interconversion proceeds through a conformational equilibrium in dipalladacycles (see picture).
