《Bulky N-Heterocyclic-Carbene-Coordinated Palladium Catalysts for 1,2-Addition of Arylboron Compounds to Carbonyl Compounds》 was written by Okuda, Yuta; Nagaoka, Masahiro; Yamamoto, Tetsuya. Quality Control of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane And the article was included in ChemCatChem in 2020. The article conveys some information:
The synthesis of primary, secondary, and tertiary alcs. by the 1,2-addition of arylboronic acids or boronates to carbonyl compounds, including unactivated ketones, using novel bulky yet flexible N-heterocyclic carbene (NHC)-coordinated 2,6-di(pentan-3-yl)aniline (IPent)-based cyclometallated palladium complexes (CYPs) as catalysts is reported. The PhS-IPent-CYP-catalyzed reactions are efficient at low catalyst loadings (0.02-0.3 mol% Pd), and the exceptional catalytic activity for 1,2-addition is attributed to the steric bulk of the NHC ligand. These reactions can yield a wide range of functionalized benzylic alcs. that are difficult to synthesize by classical protocols using highly active organomagnesium or lithium reagents. In the part of experimental materials, we found many familiar compounds, such as 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Quality Control of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane)
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.Quality Control of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane
