I found the field of Chemistry very interesting. Saw the article (Cyclopentadienone)iron-Catalyzed Transfer Dehydrogenation of Symmetrical and Unsymmetrical Diols to Lactones published in 2020. COA of Formula: C8H6O2, Reprint Addresses Funk, TW (corresponding author), Gettysburg Coll, Dept Chem, Gettysburg, PA 17325 USA.. The CAS is 87-41-2. Through research, I have a further understanding and discovery of Isobenzofuran-1(3H)-one

Air-stable iron carbonyl compounds bearing cyclo-pentadienone ligands with varying substitution were explored ,as catalysts in dehydrogenative diol lactonization reactions using acetone as both the solvent and hydrogen acceptor. Two catalysts with trimethylsilyl groups in the 2- and 5-positions, [2,S-(SiMe3)(2)-3,4-(CH2)(4)(eta(4)-C4C=O))Fe(CO)(3) (1) and [2,5-(SiMe3)(2)-3,4(CH2)(3)(eta(4)-C4C=O)]Fe(CO)(3) (2), were found to be the most active, with 2 being the most selective in the lactonization of diols containing both primary and secondary alcohols. Lactones containing five-, six-, and seven-membered rings .were successfully synthesized, and no over-oxidations to carboxylic acids were detected. The lactonization of unsymmetrical diols containing two primary alcohols occurred with catalyst 1, but selectivity was low based on alcohol electronics and modest based on alcohol sterics. Evidence for a transfer dehydrogenation mechanism was found, and insight into the origin of selectivity in the lactonization of 1 degrees/2 degrees diols was obtained. Additionally, spectroscopic evidence for a trimethylamine-ligated iron species formed in solution during the reaction was discovered.

Liu, ZK; Wang, QQ; Wang, H; Su, WT; Dong, SL in [Liu, Zhengkun; Wang, Qianqian; Wang, Hao; Su, Wenting; Dong, Shouliang] Lanzhou Univ, Sch Life Sci, Inst Biochem & Mol Biol, 222 Tianshui South Rd, Lanzhou 730000, Gansu, Peoples R China; [Dong, Shouliang] Lanzhou Univ, Key Lab Preclin Study New Drugs Gansu Prov, 222 Tianshui South Rd, Lanzhou 730000, Gansu, Peoples R China published A chloroacetate based ratiometric fluorescent probe for cysteine detection in biosystems in 2019, Cited 47. The Name is Isobenzofuran-1(3H)-one. Through research, I have a further understanding and discovery of 87-41-2.

The specific detection of cysteine (Cys) over homocysteine (Hcy), glutathione (GSH) and other amino acids is of great significance for studying its biological functions as well as for the diagnosis of related diseases. Chloroacetyl group was often used as a reaction site for cysteine fluorescent probes for its sensitivity and selectivity. However, high background fluorescence and low stability are common problems encountered by such probes. Here, four chloroacetyl group based fluorescent probes (C1, C2, C3, and H4) was synthesized for a comparative study. We found that the inefficient quenching ability of chloroacetyl group turned into an advantage when connected with a ratiometric fluorophore. With the modification of chloroacetyl group, probe H4 displayed excellent ratiometric property and great selectivity for Cys, the stability was also improved. Additionally, the probe was successfully applied for quantitative detection of Cys in fetal bovine serum and real-time imaging in living HeLa cells with low toxicity. (C) 2019 Elsevier Ltd.

A low-valent magnesium(i) complex [((Xyl)Nacnac)Mg](2) was employed as a highly efficient precatalyst for the hydroboration of a variety of cyclic and linear organic carbonates, polycarbonates, CO2 and esters with HBpin under mild conditions. The resultant boronates can be used for the preparation of the corresponding value-added diols, triols or alcohols through hydrolysis.

A ligand-free iron-catalyzed method for the oxygenation of benzylic sp(3) C-H bonds by molecular oxygen (1 atm) using a thiyl radical as a cocatalyst has been developed. This transformation provides a facile access to amides, esters and ketones from readily accessible corresponding amines, ethers and alkanes. It features high regioselectivity, mild oxidative conditions and excellent functional group compatibility, providing good opportunities to the site-selective functionalization of complex molecules. Preliminary mechanistic studies suggest that this reaction may not undergo a benzylic cation intermediate pathway and the carbonyl oxygen atom in the products may be derived from molecular oxygen.
