Cobalt-Catalyzed Arylzincation of Alkynes
, 2016 Cobalt(II) bromide catalyzes arylzincation of alkynes with arylzinc iodide•lithium chloride complexes in acetonitrile. The scope of the arylzincation is wide enough to use unfunctionalized alkynes, such as 6-dodecyne, as well as arylacetylenes.

An Engineered Supramolecular Pathway for Enhanced Electrochemiluminescence
Advanced Science, EarlyView.A supramolecular electrochemiluminescent (ECL) system is presented in which cucurbit[7]uril (CB7) is covalently linked to [Ru(bpy)3]2+, forming a recognition‐responsive emitter. Host‒guest preorganization of tri‐n‐propylamine enables intramolecular ECL, boosting intensity by 162% compared to the standard system.
