Robust Alkyne Metathesis Catalyzed by Air Stable d 2 Re(V) Alkylidyne Complexes
We report in this communication the first example of catalytic alkyne metathesis reactions mediated by well-defined non-d alkylidyne complexes. The air-stable d Re(V) alkylidyne complex , bearing two PO-chelating ligands and a labile pyridine ligand, could catalyze homometathesis of internal alkynes...

alkylidyne complexes. The air-stable d
Re(V) alkylidyne complex
, bearing two PO-chelating ligands and a labile pyridine ligand, could catalyze homometathesis of internal alkynes with a broad substrate scope, including alcohols, amines, and even carboxylic acids. The catalyst can tolerate heating, air, and moisture in both solid and solution states, and the catalytic metathesis reactions could proceed normally in wet solvents. |
