Synthesis of Dinaphtho-dioxaphosphepin-4-oxides, Epoxides and Bisphosphonates

A few new seven‐membered phosphorus heterocyclic compounds and bis‐phosphonates (5a–5g, 5f′, 5g′, 9 and 10) were prepared by the reaction of 4‐bromo dioxaphosphepin (2) with various Grignard reagents followed by their oxidation with H2O2. All the compounds were thoroughly characterized by elemental...
