Nickel-catalysed cyclopropanation of electron-deficient alkenes with diiodomethane and diethylzinc†
Abstract
In the presence of a nickel catalyst, the cyclopropanation of electron-deficient alkenes with diiodomethane and diethylzinc is drastically accelerated. A wide range of cyclopropyl ketones, esters and amides can be accessed under these conditions.
