Spirophosphoranes obtained by addition of tricoordinated phosphorus compounds on α diketones and α ethylenic ketones are discussed. Steric and electronegativity factors which determine the number of stable isomers are considered, but no interconversion mechanism is postulated. Phosphorus epimerization has been studied with compounds containing two centres of asymmetry.
