Article abstract of DOI:10.1039/P29920000835

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 1J_CH, 2J_CP', 3J_CP and 2J_PP 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).
