文摘

Compounds that have the formula M(NR)(CHR鈥?(OR鈥?(Pyrrolide), where OR鈥?is 鈥渓arge鈥?relative to NR and M = Mo or W, have been shown to be Z-selective olefin metathesis catalysts. In this communication we report a new route to Mo complexes in which the relationship between NR and OR鈥?has been reversed; i.e., the imido ligand is the sterically demanding 2,6-dimesitylphenylimido ligand (NAr*).
