Highly enantio- and diastereoenriched monofluorocyclopropanes were accessed via the Simmons-Smith fluorocyclopropanation of allylicalcoholsusing difluoroiodomethane and ethylzinc iodide as the substitutedcarbenoid precursors. The scrambling of halogens at the zinccarbenoid led to the formation of the fluorocyclopropanating agent (fluoroiodomethyl)zinc(II) fluoride. This strategy circumvented the

We report the study of the electronic structures of CHBrFI and CHClFI using HeI/HeII photoelectron spectroscopy. The orbital interactions are discussed on the basis of high-level quantum chemical calculations and empirical arguments.
