《Gold-Catalyzed Alkynylative Meyer-Schuster Rearrangement》 was published in Organic Letters in 2020. These research results belong to Banerjee, Somsuvra; Ambegave, Shivhar B.; Mule, Ravindra D.; Senthilkumar, Beeran; Patil, Nitin T.. Formula: C6H4BrNO The article mentions the following:
In the presence of a (methylbenzotriazole)(triphenylphosphine)gold(I) triflate, propargyl alcs. such as BuCCCH(OH)Ph underwent alkynylation and Meyer-Schuster rearrangement reactions with silylethynylbenziodoxolones such as TIPS-EBX to yield (E)-α-alkynyl-α,β-unsaturated ketones such as I. Mass spectroscopic observation of intermediates and control reactions indicate that a gold(III) intermediate is necessary to catalyze the Meyer-Schuster rearrangement, and that an alkynylgold(III) intermediate is formed and mediates the alkynylation reaction. In the experiment, the researchers used many compounds, for example, 2-Bromonicotinaldehyde(cas: 128071-75-0Formula: C6H4BrNO)
2-Bromonicotinaldehyde(cas: 128071-75-0) belongs to pyridine. Pyridine is widely used in the precursor to agrochemicals and pharmaceuticals. Also, it is used as an important reagent and organic solvent.Formula: C6H4BrNO
