Abstract

[Cu(NCCH₃)₄][BF₄]₂ can be heterogenized by an ion exchange method on mesoporous NaAlMCM-41 and NaAlMCM-48 materials. The heterogenized complex and the homogeneous Cu compound are applicable for the cyclopropanation of olefins at 303 K. Comparable yields are observed for non-bulky olefins, olefins with bulkier substituents lead to lower yields. [Cu(NCCH₃)₄][BF₄]₂ grafted on mesoporous surfaces (as heterogeneous catalyst) are relatively stable and recyclable for several catalytic runs with only slight decrease in catalytic activity.
