72287-26-4,A common heterocyclic compound, 72287-26-4,[1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

c) N1-[2-phenyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-phenyl]-1-benzenesulfonamide. A mixture of the N1-(4-bromo-2-phenylbenzene)-1-benzenesulfonamide (0.388 g, 1.00 mmol), bis(pinacolato)diboron (0.305 g, 1.20 mmol), potassium acetate (0.294 g, 3.00 mmol) and [1,1′-bis(diphenylphosphino) ferrocene]dichloropalladium(II) (25 mg, 0.030 mmol) in DMF (10 ml) was heated under an atmosphere of nitrogen at 100¡ã C. for 16.5 hours. The DMF was evaporated in vacuo and the residue purified by silica gel flash chromatography using methylene chloride/heptane 7:3 plus 2percent triethyl amine to provide N1-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-phenylbenzene]-1-benzenesulfonamide (0.135 g) as an oil. tR=23.13 min (RP-HPLC, 25-100percent acetonitrile-0.1percent TFA, 25 min); low resolution MS m/e 434 (M-H+)

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand 72287-26-4 reaction routes.
