The reaction of 4,7-phenanthroline (1) with some substituted benzoyl chlorides and trimethyl phosphite in the presence of sodium iodide gave the corresponding α,α'-diphosphonates, α,γ'-diphosphonates, α-phosphonates, and γ-phosphonates respectively. 3,8-Diphosphonates (2a1, 2a2) were separated by thin layer chromatography and the crystal structure of 2a2 was determined by X-ray analysis.
