An Isolable Fused‐Metallacyclobutadiene Intermediate Enables Z ‐Selective Alkyne Dimerization via a Non‐Classical CCC ‐Pincer Platform

Pincer complexes are privileged platforms in homogeneous catalysis, yet genuinely all‐carbon (CCC) variants remain uncommon and generally rely on N‐heterocyclic carbene auxiliaries for structural stabilization. This scarcity has limited understanding of how a meridional all‐carbon donor array can regulate substrate...
