Mercuric Triflate-Catalyzed Synthesis of 2-Methylfurans from 1-Alkyn-5-ones

Mercuric Triflate-Catalyzed Synthesis of 2-Methylfurans from 1-Alkyn-5-ones

2-Methylfurans were prepared by an effective cyclization of 1-alkyn-5-ones in the presence of mercuric triflate as the catalyst under very mild reaction conditions with high catalytic turnover up to 100 times. Benzene, toluene, or dichloromethane was the solvent of choice.
