The first successful direct metallation of ethene
Abstract
Vinyl potassium was formed directly from ethene by use of a new butyl-lithium–potassium t-butoxide–tetramethylethylenediamine metallating reagent; typical products were obtained with 1-bromo-octane and, after addition of LiBr in tetrahydrofuran, with benzaldehyde and diphenyl disulphide.
