摘要

Highly active alkyne-metathesis catalysts have been realized by exchanging the amide ligands on molybdenum (vi) alkylidyne trisamide complexes 1 with simple phenols,[1, 2] such as 4-nitrophenol, or by use of chlorotrisamide Mo (iv) complexes.[3] In spite of this practical utility, these catalysts can become deactivated over time, apparently through a bimolecular dimerization pathway.[4] The polymerization of 2-butyne, the metathesis by- ...
