Carbocyclic pincer carbene complexes of ruthenium: syntheses and reversible hydrogenation
The ruthenium carbene pincer complex 2 was synthesized treating the benzo annulated cycloheptatriene bisphosphine 1 with RuCl 3 . Addition of three equivalents of hydrogen to the carbocyclic carbene complex 2 was achieved in reaction of 2 with hydrogen at elevated temperatures. Hydrogenated complex...

| description | The ruthenium carbene pincer complex
2
was synthesized treating the benzo annulated cycloheptatriene bisphosphine
1
with RuCl
3
. Addition of three equivalents of hydrogen to the carbocyclic carbene complex
2
was achieved in reaction of
2
with hydrogen at elevated temperatures. Hydrogenated complex
4
, exhibiting a rigid chair conformation in solution, was dehydrogenated by heating a toluene solution of complex
4
to reflux for 5-7 d. In reaction with ethylene, complex
4
transfers one equivalent of hydrogen, forming ethane and alkyl complex
5
.
Double C-H activation leads to the formation of a ruthenium carbocyclic carbene PCP pincer complex. Uptake and release of three equivalents of hydrogen involving the cycloheptatriene moiety acting as a cooperative ligand was realized. |
