Reaction Conditions:
with (triphenylphosphine)gold(I) chloride;water;silver trifluoromethanesulfonate in methanol at 25; for 12 h;
Steps:
15 Example 15:
Add 0.2mmol α-alkynyl ketones in a reaction tube 10mL R1is ethyl, R2is phenyl, 0.005mmol of PPh3AuCl, 0.006mmol of AgOTf, 2mmol of H2O, 1mL of methanol, stirred for 12h in air atmosphere at 25 °C. After completion of the reaction, rotary evaporation, product was separated by column chromatography to give the following: 1-phenyl-1,3-pentanedione (1-phenylpentane-1,3-dione). Oily liquid, yield 96%,
