What Makes A Good Nucleophile? – Master Organic Chemistry - Chemical reactivity and the concept of charge- and frontier-controlled reactions Gilles Klopman Journal of the American Chemical Society 1968, 90 (2), 223-234 DOI: 1021/ja01004a002 Tables IX and X also support the same nucleophilicity order on the basis of MO calculations. This paper is the origin of the familiar “Klopman equation”, which ...

Jr. Supplemental Tables of Molecular Orbital Calculations, Volume 2; Pergamon Press: Oxford, 1965; Recognition of stereochemical paths by orbital interaction Kenichi Fukui Accounts of Chemical Research 1971 4 (2), 57-64 DOI: 10.1021/ar50038a003 This paper discusses the molecular orbitals of ...
Frontier molecular orbital theory - Wikipedia - History. In 1952, Kenichi Fukui published a paper in the Journal of Chemical Physics titled "A molecular theory of reactivity in aromatic hydrocarbons." Though widely criticized at the time, he later shared the Nobel Prize in Chemistry with Roald Hoffmann for his work on reaction mechanisms. Hoffman's work focused on creating a set of four pericyclic reactions in organic chemistry, based on ...
1,3-Dipolar cycloaddition - Wikipedia - 1,3-dipolar cycloaddition reactions have emerged as powerful tools in the synthesis of complex cyclic scaffolds and molecules for medicinal, biological, and mechanistic studies. Among them, [3+2] cycloaddition reactions involving carbonyl ylides have extensively been employed to generate oxygen-containing five-membered cyclic molecules.

Axial Redox Tuning at a Tetragonal Cobalt Center ... - Square pyramidal cobalt complexes were prepared to study their multielectron redox properties. To build a stable redox-active cobalt complex, the combination of a tridentate acriPNP (acriPNP– = 4,5-bis(diisopropylphosphino)-2,7,9,9-tetramethyl-9H-acridin-10-ide) ligand with a bidentate ligand, such as 2,2′-bipyridine, 2-(o-phenyl)pyridine, biphenylene, and their analogues, was employed. In ...

Synthesis and Characterization For the synthesis of target molecules of the D-A-D type, we studied the Suzuki– Miyaura cross-coupling reactions of 4,7-dibromobenzo[c] [1,2,5]chalcogenadiazoles 2(a–c) with two equivalents of the donor boronic ester 3 in the presence of Pd(PPh3)4 as a catalyst and aqueous solution ...
Transition Metal Carbonyls - - Pauling ; The Nature of the Chemical Bond, 3rd Ed.;1960, pg. 172. • CO also has the ability to stabilize polyanionicspecies by acting as a strong π acceptor and delocalizing the negative charge over the CO oxygens . • Na 4[Cr(CO)4] has the extraordinarily low ν(CO) of 1462 cm −1, the extremely high anionic charge on the complex, and ion pairing of Na + to the carbonyl oxygen ...
Inorganic Chemistry - Soka - reactions, and physical properties. However, classical chemical knowledge is essential before studying new chemistry. Learning synthetic methods, structures, bondings, and main reactions of basic compounds is a process requisite to students. This text book describes important compounds systematically along the periodic
