《Vinylidenation of Organoboronic Esters Enabled by a Pd-Catalyzed Metallate Shift》 was written by Aparece, Mark D.; Gao, Chenpeng; Lovinger, Gabriel J.; Morken, James P.. COA of Formula: C12H17BO2This research focused onvinylidenation organoboronic ester palladium catalyzed metalate shift; disubstituted alkenyl boronic ester preparation vinyl insertion reaction; allyl complexes; boron; homogeneous catalysis; palladium. The article conveys some information:
Organoboron “”ate”” complexes undergo a net vinyl insertion reaction to give 1,1-disubstituted alkenyl boronic esters when treated with stoichiometric allyl acetate and a palladium catalyst. Reactions that employ vinyllithium afforded good to excellent yields after one hour, while reactions that employ vinylmagnesium chloride furnished modest to good yields after 18 h. In the experiment, the researchers used many compounds, for example, 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6COA of Formula: C12H17BO2)
4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6) also known as boronate ester, is generally used in metal-catalyzed C-C bond formation reactions like Suzuki–Miyaura reaction.COA of Formula: C12H17BO2
