Halomethylmetal Mediated Cyclopropanation Reactions 1. Introduction Emschwiller firstly reported that diiodomethane reacted with zinc to give iodomethylzinc species in 1929. Simmons and Smith found that (IZnCH2I) could be used for the stereospecific conversion of alkenes to cyclopropanes in 1958. Emschwiller, G. Compt. Rend. 1929,188,1555 Simmons, H. E.; Smith, R. D. J. Am. Chem. Soc. 1958, 80, 5323 6
