Three synthetic procedures have developed for a new class of phosphorus-ylide containing conjugate heterocycles, 3-oxo-λ5-benzophospholes. The key to the heterocycle is unusual intramolecular acylation of phosphorus-ylide forming an endocyclic ylide. Several types of 2-substituted benzophospholes are synthesized, some of which showed a fluorescence.
Keywords:
