Abstract

Abstract Fluoroenylidenetriphenylphosphorane (1a) reacts with maleic and phthalic anhydrides to give lactones 2a and 3, respectively. The same reagent (1a) extrudes sulphur from thiophthalic anhydride yielding the spiro-1, 3-indandione derivative 4. The infrared and mass spectra of the new products are discussed.
