The crystalstructures of three (N-phenylthioureidoalkyl- and -aryl)phosphonates, i.e. diphenyl [(3-phenylthioureido)phenylpropyl]phosphonate, diphenyl [1-(3-phenylthioureido)benzyl]phosphonate and diphenyl [2,2-dimethyl-1-(3-phenylthioureido)propyl]phosphonate, have been determined by X-ray diffraction. The conformations of the title molecules, the geometry of the thioureide fragments and molecular

The first successful enantioseparation of representative O,O‐diphenyl‐N‐arylthioureidoalkylphosphonates, (±)‐Ptc‐ValP(OPh)2 & (±)‐Ptc‐LeuP(OPh)2 and thiourylenedi(isobutyl phosphonate), Tcm[ValP(OPh)2]2 on analytical and semipreparative scale was achieved by high‐performance liquid chromatography using polysaccharide‐based chiral stationary phases (CPs). Atc‐AAP(OPh)2 was obtained using modified tricomponent
