Abstract
The new (porphyrin)ruthenium(II) carbene complex 1 has been prepared by treating (TPP)Ru(CO)(EtOH) with excess 2,6-di-tert-butyl-4-methylphenyl diazoacetate and characterized by X-ray crystal structure analysis due to a kinetic stability. The reactivity of 1 toward axial ligands (CO, pyridine, dimethylphenylphosphine) and the asymmetric cyclopropanation of styrene with this bulky diazoacetate ester catalyzed by ruthenium Halterman porphyrin are also presented.
