In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called An excursion in the second-order nonlinear optical properties of platinum complexes, published in 2021-11-01, which mentions a compound: 1008-89-5, mainly applied to review platinum complex photochromism hyperpolarizability ddipole moment, COA of Formula: C11H9N.

A review. Electrooptical devices and optical communications need compounds with second-order nonlinear optical (NLO) properties as construction blocks. Typically, to show a large quadratic hyperpolarizability, a compound should be asym., be characterized by a large variation between the dipole moments in the excited and ground states, and have low energy electronic transitions. For example, a large quadratic hyperpolarizability can be reached when an electron-donor moiety is linked by means of a π-conjugated spacer to an acceptor group. In the field of second-order nonlinear optics, particularly attractive are coordination metal complexes because they are often characterized by low-energy and high-intensity intraligand (IL), ligand-to-metal (LM), and metal-to-ligand (ML) charge transfer (CT) electronic transitions, that can be regulated by the choice of the metal and ligands. Among them, platinum(II) complexes are captivating. During this excursion, we will see the quadratic hyperpolarizability of many of them. After some basic NLO notions, the review presents various classes of NLO-active platinum compounds having mono- and bidentate nitrogen ligands (pyridine, bipyridine, phenanthroline), dithiolenes, cyclometalated ligands (imines, phenylpyridine, phenylbipyridine, and dipyridylbenzene), alkynyl ligands. It is shown how to regulate the quadratic hyperpolarizability with suitable ligands and how to photomodulate the NLO properties by means of a dithienylethene (DTE) moiety. Some examples of complexes with redox-switchable NLO properties are also given. Although the accent is on the quadratic hyperpolarizability measured in solution, it is also shown how some NLO-active platinum complexes can be nano-organized to afford thin films with nonlinear optical properties. The report is not comprehensive, but it allows to get into the field of NLO-active platinum compounds and to understand their potential.

Alternatively, I were also prepared by cyclization of amidines RC6H4NHC(:NH)R1 (II) by successive treatment with aqueous NaOCl and then with Na2CO3. Cyclization of II (R = C-3 substituted) by the latter method gave mixtures of C-7 and C-5 substituted benzimidazoles which were separated by crystallization Acidities of II increased with increasing electron withdrawing power of R, and, as the acidity of II increased, yields of I from cyclization of II decreased.

Product Details of 132098-59-0. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Bis((S)-4-phenyl-4,5-dihydrooxazol-2-yl)methane, is researched, Molecular C19H18N2O2, CAS is 132098-59-0, about Concise Enantioselective Synthesis of Oxygenated Steroids via Sequential Copper(II)-Catalyzed Michael Addition/Intramolecular Aldol Cyclization Reactions. Author is Cichowicz, Nathan R.; Kaplan, Will; Khomutnyk, Yaroslav; Bhattarai, Bijay; Sun, Zhankui; Nagorny, Pavel.

A new scalable enantioselective approach to functionalized oxygenated steroids is described. This strategy is based on chiral bis(oxazoline) copper(II) complex-catalyzed enantioselective and diastereoselective Michael reactions of cyclic ketoesters and enones to install vicinal quaternary and tertiary stereocenters. In addition, the utility of copper(II) salts as highly active catalysts for the Michael reactions of traditionally unreactive β,β’-enones and substituted β,β’-ketoesters that results in unprecedented Michael adducts containing vicinal all-carbon quaternary centers is also demonstrated. The Michael adducts subsequently undergo base-promoted diastereoselective aldol cascade reactions resulting in the natural or unnatural steroid skeletons. The exptl. and computational studies suggest that the torsional strain effects arising from the presence of the Δ5-unsaturation are key controlling elements for the formation of the natural cardenolide scaffold. The described method enables expedient generation of polycyclic mols. including modified steroidal scaffolds as well as challenging-to-synthesize Hajos-Parrish and Wieland-Miescher ketones.
