The preparation and constitution of γ-acylpropenylphosphonium salts have been described. The oxidation of these salts with derivatives of HNO2 yielded the yet unknown γ-oximinophosphonium salts and their corresponding nitrosophosphoranes. A new rearrangement of γ-oximinophosphonium salts has been described.
