Electric Literature of 767-91-9, A common heterocyclic compound, 767-91-9, name is 2′-Methoxyphenyl acetylene, molecular formula is C9H8O, 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.
General procedure: A mixture of aryl iodide (2 mmol), aryl alkyne (2.4 mmol), Ni(OAc) 2 (10 mol %), Et3N (6 mmol) and 1,4-dioxane (15 mL) were charged into the reactor (steel bomb). The reactor was closed and pressurized to ~2bar CO and then stirred at 100 C for 4 h. The reaction Progress was monitored by TLC. The reaction mixture was cooled to room temperature, before being filtered through a pad of Celite. The filtrate was concentrated and purified by silica gel with a mixture of hexane and ethyl acetate to give the pure product. For all examples, reactions were performed on 100 mg scale of corresponding aryl iodides.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
