In 2019,Organic Letters included an article by Ju, Baihang; Chen, Shigui; Kong, Wangqing. Product Details of 1779-49-3. The article was titled 《Pd-Catalyzed Enantioselective Double Heck Reaction》. The information in the text is summarized as follows:
An asym. Pd-catalyzed intra- followed by an intermol. double Heck reaction of arenediazonium salts with simple alkenes is disclosed. This reaction features mild reaction conditions, simple operation and excellent functional group tolerance, provides a rapid access to functionalized dihydrobenzofurans bearing all-carbon quaternary centers in good regioselectivity (>95/5) and enantioselectivity (90-99% ee). The results came from multiple reactions, including the reaction of Methyltriphenylphosphonium bromide(cas: 1779-49-3Product Details of 1779-49-3)
Methyltriphenylphosphonium bromide(cas: 1779-49-3) is an organophosphorus compound, with potential use as a precursor and a solvent in organic synthesis. And it is used widely for methylenation via the Wittig reaction.Product Details of 1779-49-3
