Convenient synthesis of dicyclohexyldithiophosphinic acid
Dicyclohexyldithiophosphinic acid was synthesized by a three-step strategy through the Grignard reaction of PSCl3 with cyclo-C6H 11MgBr and the P-P bond-cleavage reaction of the intermediate. The 1H NMR data of ammonium dicyclohexyldithiophosphinate 4 and dicyclohexyldithiophosphinic acid 5 were characterized by 1H- 1H correlation spectra. Copyright Taylor & Francis Group, LLC.
