《Iron-Catalyzed Direct Cross-Coupling of Ethers and Thioether with Alcohols for the Synthesis of Mixed Acetals》 was written by Han, Wei; Cheng, Lu; Zhao, Hongyuan. COA of Formula: C7H9NO And the article was included in Synlett in 2020. The article conveys some information:
An iron-catalyzed direct O-alkylation of alcs. via α-C(sp 3)-H activation of ethers and a thioether was established that tolerates cyclic and acyclic ethers and alcs. containing aromatic N-heterocyclic moieties, providing an efficient and green method for the synthesis of mixed acetals with good to excellent yields. The robustness of this protocol is demonstrated by the late-stage oxidation of a structurally complex natural product. The experimental part of the paper was very detailed, including the reaction process of 2-(2-Hydroxyethyl)pyridine(cas: 103-74-2COA of Formula: C7H9NO)
2-(2-Hydroxyethyl)pyridine(cas: 103-74-2) belongs to pyridine. Pyridine is a relatively complex molecule and exhibits a number of different bands in IR spectra. Among others, the bands characterizing the ν8a and ν19b modes have been found to be sensitive to the coordination or protonation of the molecule. Note that the band that is diagnostic for the PyH+ ion at about 1545 cm− 1 (ν19b mode) does not overlap with any of the other bands.COA of Formula: C7H9NO
