2-(5-Methyl-2-Phenyl-2H-1,2,3-Dizaphosphol-4-YL)-4H-Benzo[D]-1,3,2-Dioxaphosphorin-4-One in the Synthesis of Bis-Heterocyclic 1,4,2-Oxazaphosphepine Derivatives

The reaction of 2-(5-methyl-2-phenyl-2H-1,2,3-dizaphosphol-4-yl)-4H-benzo[d]-1,3,2-dioxaphosphorin-4-one with arylimines leads to the formation of seven-membered heterocycles, 3-aryl-2-(5-methyl-2-...
