With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.29841-69-8,(1S,2S)-(-)-1,2-Diphenylethylenediamine,as a common compound, the synthetic route is as follows.
(2); Synthesis of Rh+{2,2′-bis(diphenylphosphinyl)benzophenone} {(S,S)-DPEN}(SbF6-); Into [Rh+{2,2′-bis(diphenylphosphinyl)benzophenone}(cod)](SbF6-) obtained in the (1) after the distillation under reduced pressure were added 21.2 mg (0.1 mmol) of (S,S)-DPEN and 2 ml of methylene chloride, and then the solution was stirred under hydrogen atmosphere for 1 hour. The solvent was distilled off under reduced pressure and then the residue was dried to give 110 mg (yield: > 99%) of the title compound. 31p NMR (CDCl3) delta ppm; 48.28, 57.04 (2dd, Jp-p = 40.5 Hzo, Jp-Rh = 157.9 Hzo).
29841-69-8, As the paragraph descriping shows that 29841-69-8 is playing an increasingly important role.
