And the article was included in ACS Catalysis in 2011.Quality Control of 2-(Bromomethyl)-2-phenyl-1,3-dioxolane This article mentions the following:
Orthogonal σ,π-bisfunctionalization of terminal alkynes can be achieved with a cationic gold complex in catalytic amounts First, the terminal C-H bond is transformed to the corresponding bromoalkyne which is then activated toward nucleophilic attack. This reactivity correlates with the structural nature of isolated gold-alkyne complexes. In the experiment, the researchers used many compounds, for example, 2-(Bromomethyl)-2-phenyl-1,3-dioxolane (cas: 3418-21-1Quality Control of 2-(Bromomethyl)-2-phenyl-1,3-dioxolane).
2-(Bromomethyl)-2-phenyl-1,3-dioxolane (cas: 3418-21-1) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. 1,3-Benzodioxole can be synthesized from catechol with disubstituted halomethanes.Quality Control of 2-(Bromomethyl)-2-phenyl-1,3-dioxolane
