Podand prevents polymers : The molybdenum(VI) propylidyne catalyst 1 with a podand triphenolamine ligand shows high activity in the metathesis of a variety of alkyne substrates, including heterocycles that contain donor moieties. With one substrate‐binding site blocked by the multidentate ligand, the undesired polymerization of small alkynes that occurs with non‐podand‐ligand complex 2 is completely inhibited.
