A Novel Synthesis of Phenyleneethynylenes by Using Ph2P(O)-protected Ethynes
Typical Procedure1a):
A toluene (10 mL) solution of 4-ethynylanisole (132 mg, 1.0 mmol), CuI (19 mg, 0.1 mmol), Ph2PCl (265 mg, 1.2 mmol) and Et3N (202 mg, 2.0 mmol) is stirred at 80 °C for 8 h. After workup with CH2Cl2 and NH4Cl(aq), the combined organic layer is washed with brine, and dried over MgSO4. After evaporation, the residue is purified by column chromatography on silica gel (eluent: hexane/CH2Cl2 = 6/1-4/1) to give ((4-methoxyphenyl)ethynyl)diphenylphosphine as pale yellow sticky gel (193 mg, 61%).
To a THF (10 mL) solution of ((4-methoxyphenyl)ethynyl)diphenylphosphine (316 mg, 1.0 mmol) is added H2O2(aq) (30%, 2.5 mL, 20 mmol) at 0 °C, and the mixture is stirred at rt for 2 h. After workup with CH2Cl2 and water, the combined organic layer is washed with brine and dried over MgSO4. After evaporation, the residue is purified by column chromatography on silica gel (eluent: hexane/AcOEt = 2/1) to afford ((4-methoxyphenyl)ethynyl)diphenylphosphine oxide as white powder (312 mg, 94%).
To a THF solution (10 mL) of ((4-methoxyphenyl)ethynyl)diphenylphosphine oxide (166 mg, 0.5 mmol) is added t-BuOK (84 mg, 0.75 mmol), and the mixture is stirred at rt for 2 h. After workup with CH2Cl2 and NH4Cl(aq), the combined organic layer is washed with brine and dried over MgSO4. After evaporation, the residue is purified by column chromatography on silica gel (eluent: hexane) to afford 4-ethynylanisole as pale yellow oil (60 mg, 91%).
A toluene (10 mL) solution of 4-ethynylanisole (132 mg, 1.0 mmol), CuI (19 mg, 0.1 mmol), Ph2PCl (265 mg, 1.2 mmol) and Et3N (202 mg, 2.0 mmol) is stirred at 80 °C for 8 h.

Mukaiyama Oxidation-Reduction Condensation
[Experimental procedure]
to a mixture of alkoxydiphenylphosphine (2, 0.60 mmol), prepared from the alcohol (1), n-BuLi and chlorodiphenylphosphine, and tetrafluoro-1,4-benzoquinone (0.72 mmol) under argon atmosphere is added a dichloromethane (0.50 mL) solution of alcohol (3, 0.72 mmol) at room temperature. After the reaction that is monitored by TLC was completed, the reaction mixture is quenched by adding water and the aqueous layer is extracted with dichloromethane. The organic layers are dried over anhydrous sodium sulfate. After filtration and evaporation, the resulted residue is purified by preparative TLC to afford the corresponding ether (4).
