Abstract: New boron derivatives of dithiophosphonic acids 3a – c and 5 were obtained in the reactions of Lawesson’s reagent la and its homologue lb with trialkyl borates 2a – c and O-isobutyl diphenylborate 4. Low frequency ultrasound irradiation (22 kHz, power 130 W) leads to reduction in reaction temperature and time in the reactions studied. The prepared compounds were identified by IR, 1H, and 31P NMR and mass spectra as well as elemental analyses.
