Ru<sub>3</sub>(CO)<sub>12</sub>-Catalyzed Reactions of Catechols with Alkynes: An Atom-Economic Process for the Synthesis of 2,2-Disubstituted 1,3-Benzodioxoles from the Double Addition of the O−H Bond Across a Triple Bond

Ru3(CO)12 has been found to be the efficient catalyst for the addition reactions of catechols with both terminal and internal alkynes to selectively afford 2,2-disubstituted 1,3-benzodioxoles in good to high yields. The formation of 2,2-substituted 1,3-benzodioxoles results from the tandem addition of two O-H bonds of catechols to alkyne's triple bond.
