Yield: 92%

Reaction Conditions:

with indium(III) triflate;water;toluene-4-sulfonic acid in 1,2-dichloro-ethane for 4 h;Sealed tube;Reflux;regioselective reaction;

Steps:

6.5 4.2 General procedure for the hydration of alkynes 1a-1n and 1p-1t
General procedure: The reaction mixture of In(OTf)3 (11.2 mg, 2 mol %), PTSA (57.1 mg, 30 mol %), DCE (2.0 mL), alkynes 1a-1n or 1p-1t (1.0 mmol) and water (0.2 mL) in a 10 mL flask or in a 10 mL sealed tube was stirred at reflux and monitored periodically by TLC. Upon completion, DCE was removed under reduced pressure using an aspirator, and then the residue was purified by flash chromatography (PE/EA) on silica gel to afford corresponding carbonyl compounds 2a-2n or 2p-2t.
