HPLC of Formula: 72824-04-5, Allylboronic acid pinacol ester is a useful research compound. Its molecular formula is C9H17BO2 and its molecular weight is 168.04 g/mol. The purity is usually 95%.
Allylboronic acid pinacol ester is an allylation reagent that is used to produce aldehydes from ketones. It reacts with water, yielding the desired product and formaldehyde as a byproduct. The reaction proceeds through a sequence of steps, in which the boronate ester first reacts with water to form an allylboronate ion and hydrogen gas. This intermediate then reacts with potassium t-butoxide to produce the desired allyl alcohol and potassium borohydride. Finally, the palladium complex catalyst reduces the carbonyl group of the starting material, converting it into an aldehyde. Allylboronic acid pinacol ester is commercially available as a white solid, but can also be synthesized from 2-chloro-5-pinacolylborane (pinacol) in high yield using catalytic cross coupling reactions., 72824-04-5.

Two implementations are employed, the direct and indirect methods. HPLC of Formula: 72824-04-5
Vosahlo, Petr;Schulz, Jiri;Cisarova, Ivana;Stepnicka, Petr research published 《 Cyclopalladation of a ferrocene acylphosphine and the reactivity of the C-H activated products》, the research content is summarized as follows. Acylphosphines are an attractive subclass of phosphine ligands with specific reactivity and ligating properties. This study describes the synthesis of a ferrocene-based acylphosphine, FcC(O)PPh2 (1, Fc = ferrocenyl), the corresponding phosphine chalcogenides FcC(O)P(E)Ph2 (E = O, S and Se), and palladium(II) complexes resulting from the orthometalation of 1, viz. [Pd(μ-X)(1 – H)]2 (2-X, where X = Cl, Br and I), which in turn serve as a convenient entry point to a range of monopalladium complexes. Thus, the cleavage of 2-X with phosphines, 4-(dimethylamino)pyridine and in situ-generated 1,3-dimesitylimidazolin-2-ylidene (L) provided complexes [PdX(L)(1 – H)] (3–5), which are typically obtained as single isomers by crystallization but undergo spontaneous isomerization in solution leading to equilibrium mixtures of cis and trans isomers. Upon treatment with sodium acetylacetonate (Na(acac)), 2-Cl was transformed into [Pd(acac)(1 – H)] (6), which reacted with (diphenylphosphino)acetic acid under proton transfer to give [Pd(Ph2PCH2CO2-κ2O,P)(1 – H)] (7), while the reaction with allylating agents produced the π-allyl complex [Pd(η3-C3H5)(1 – H)] (9). Compound [PdCl(PMe3)(1 – H)] was further used to prepare a series of diorganopalladium complexes [Pd(R)(PMe3)(1 – H)] (8; R = Me, 4-C6H4Me, 4-C6H4CF3, CH:CHC6H4Me-4 and CCC6H4Me-4). All compounds were structurally characterized using spectroscopic methods and, in most cases, also by X-ray diffraction anal. The structural data indicated the rigidity of the Pd(1 – H)+ fragment and revealed variations in the Pd-donor distances dictated by an interplay between the trans influence and steric demands of the ligands surrounding Pd(II). Moreover, some compounds were studied by DFT to rationalize their isomerization equilibrium and electrochem. properties, which were examined by cyclic voltammetry.
