Reference of 768-70-7, A common heterocyclic compound, 768-70-7, name is 3-Ethynylanisole, 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: Preparation of Copper Acetylides; Procedure 1To a solution of CuI (3.8 g, 20.0 mmol) in a mixture of NH4OH(28% NH3 solution, 50 mL) and EtOH (30 mL) was added the alkyne1 (10.0 mmol) dropwise. The deep blue reaction mixture wasstirred overnight at r.t. under argon and the yellow precipitate wascollected by filtration and successively washed with NH4OH (10%NH3 solution, 3 × 50 mL), H2O (3 × 50 mL), EtOH (3 × 50 mL), andEt2O (3 × 50 mL). The bright yellow solid was then dried under highvacuum overnight to afford the desired polymeric copper acetylide2, which was used without further purification.
The synthetic route of 768-70-7 has been constantly updated, and we look forward to future research findings.
