Bisphosphonic Compounds. Part 3. Preparation and Identification of Tetraalkyl Methylene- and (α-Halomethylene)bisphosphonates by Mass Spectrometry, NMR Spectroscopy and X-Ray Crystallography

The preparation and identification of tetraalkyl methylenebisphosphonates (XYC2; X = Y = H, Cl or Br and R = alkyl) have been studied.Detailed procedures are given for the synthesis of XYC2 (X = Y = H; R = hexyl; X = Y = Cl or Br and R = Me). 1H, 13C and 31P NMR data are reported including 1JCH, 2JCP', 3JCP and 2JPP coupling constants.The fragmentation of 19 XYC2 has been studied in the gas phase.The solid state structures are given for two compounds (X = Y = Cl, R = Pri and X = Y = Br, R = Me).
