摘要

Sir: The cyclopropanation of olefins is a highly useful synthetic operation in organic synthesis. The importance of this transformation stems from the occurrence of cy- clopropane rings in many natural products and from the utility of cyclopropanes as synthetic intermediates for ring expansions and chain e1aborations.l Here we wish to report a highly convenient and versatile method for the synthesis of cyclopropanes from olefins which was found to ...
