Triphenylphosphine → HCID 68690984, compound

Participants

Reaction Steps

50 ml (0.36 M) of methyl 2-bromobenzoate, 930 mg (3.56 mM) of triphenylphosphine and 316 mg (1.78 mM) of PdCl2 are added to 1200 ml of diethylamine in a 2000 ml reactor. After stirring at room temperature for 5 minutes, 27 ml (0.36 M) of 3-butyn-1-ol and 680 mg (3.56 mM) of CuI (1) are added. The reaction medium is then stirred at 20° C. for 120 hours, the solvent is then evaporated off and the residue obtained is then purified by chromatography on silica, using dichloromethane as eluent. After evaporation, 46.7 g of a brown oil are thus obtained (64% yield).
