New efficient ruthenium metathesis catalyst containing chromenyl ligand

A synthesis of new Hoveyda–Grubbs-type catalyst with chromenyl ligand was described herein. The new catalyst was tested in model RCM and CM reactions. The catalyst proved to be quite efficient. It showed activity comparable or superior to that of commercially available Grubbs second-generation complexes.
