• Allenes
• Diphenylphosphoryl allyl alcohols
• Phosphaheterocycles
• Bronsted and Lewis acids

1-(Diphenylphosphoryl)alka-1,2-dienes, bearing aryl substituents at the allene system, under the action of Bronsted (TfOH, H2SO4) or Lewis (AICl(3)) acids gave rise to 3-hydroxyalk-2-en-1-yl-diphenylphosphine oxides (diphenylphosphoryl ally! alcohols) in yields of 57-98%. In some cases, the formation of (diphenylphosphoryl)indenes and phosphaheterobicyclic structures was observed.
