Abstract
Preparation of o-hydroxyaroylmethyltriarylphosphonium(arsonium) bromid es by reaction of substituted o-hydroxy-omega-bromoacetophenones with triarylphosphines (arsines) and their subsequent conversion into ydrox yaroylmethylenetriarylphosphoranes(arsoranes) on treatment with sodium ethoxide are described. The possibility of prototropic and conformati onal transformations of the resulting ylides is discussed on the basis of H-1 NMR and IR spectra.
