(2,6-Dichloropyridin-4-yl)boronic acid (cas: 1072951-54-2) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. HPLC of Formula: 1072951-54-2

Gram-Scale Synthesis of β-(Hetero)arylethenesulfonyl Fluorides via a Pd(OAc)2 Catalyzed Oxidative Heck Process with DDQ or AgNO3 as an Oxidant was written by Zha, Gao-Feng;Bare, Grant A.

A practical oxidative Heck reaction between organoboronic acids and ethenesulfonyl fluoride (ESF) was developed. Aryl- and heteroaryl-boronic acids reacted efficiently and stereoselectively with ESF in the presence of a catalytic amount of Pd(OAc)2 and 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) or AgNO3 in AcOH to afford the corresponding E-isomer of β-arylethenesulfonyl fluoride products. The utility of this reaction was exemplified by an expanded scope of 47 examples including N-, O-, and S-containing heteroaromatics, demonstrating chemoselectivity over aryliodides and gram-scale operation without the requirement for strict anhydrous or oxygen-free conditions. Furthermore, this procedure discriminated against the formation of arylboronic acids homo-coupling byproducts. In addition, the preparation of the first aryl vinylsulfonate polymer, a material with functionalizable Michael acceptor sites, from a starting arylboronic acid was described. In the experiment, the researchers used many compounds, for example, (2,6-Dichloropyridin-4-yl)boronic acid (cas: 1072951-54-2HPLC of Formula: 1072951-54-2).
