N-Hydrazine cyclic(amino)(alkyl)carbene ruthenium complexes: synthesis and reactivity in olefin metathesis

Key Points

• The ruthenium complex exhibited excellent catalytic performance in various metathesis reactions under air.
• Good reactivity was noted in ring-closing metathesis, ring-opening cross-metathesis, and ethenolysis.
• The N-hydrazine cyclic(amino)(alkyl)carbene ligand contributed to the stability and activity of the complex.
• Catalytic tests demonstrated efficiency in both self-metathesis and cross-metathesis reactions under atmospheric conditions.
