Cyclopropanation of alkenes catalyzed by metallophthalocyanines

Metallophthalocyanines bearing substituents especially electron-withdrawing substituents are found to be efficient catalysts for cyclopropanation of alkenes with EDA. The influences of reaction conditions have been studied, leading to the highest yield of 91% for styrene by using fluoro-substituted ruthenium–phthalocyanine complex.
