The Pd-catalyzed reaction of β-arylaminochromium(0) carbene complexes produces by transmetalation the first isolated and X-ray structurally characterized bis-Pd(II) carbene complex, as well as other alternative reaction pathways, such as the oxidative addition−transmetalation sequence, not seen before in this chemistry.
