The title compound was prepared by stirring 3-triphenylphosphoranylidene dihydro-2,5-furandione (5.0 g, 0.014 mole) for 48 hours in 100 ml water. The solid residue was isolated by filtration and air-dried to give essentially quantitative yields of a product as a white crystalline solid whose IR spectrum and elemental analysis corresponded to the structure ##STR8##
