With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13991-08-7,1,2-Bis(diphenylphosphino)benzene,as a common compound, the synthetic route is as follows.
Similar proceduredescribed for 2a was used in the synthesis of 5a using dppbz instead of dppe to obtain a pale yellow solid. Yield:70%. 31P-NMR (121.42 MHz, 298 K, CDCl3): 62.3 ppm(d, 1J(Rh-P) = 134 Hz). 1H-NMR (300 MHz, 298 K,CDCl3): 7.59-6.83 (m, Ph ? P – C6H4 – P). ESI-MS(?)m/z: 995.0 ([M-3 Ph]?, calc.: 994.9). IR (KBr, cm-1):1973 versus, m(C:O).
13991-08-7, 13991-08-7 1,2-Bis(diphenylphosphino)benzene 498379, achiral-phosphine-ligands compound, is more and more widely used in various fields.
