What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Catalysis
  • Alkene

Kiyohiko Nakajima mostly deals with Organic chemistry, Catalysis, Medicinal chemistry, Schiff base and Stereochemistry. Kiyohiko Nakajima interconnects Combinatorial chemistry and Molybdenum in the investigation of issues within Catalysis. His studies in Medicinal chemistry integrate themes in fields like Carbon–carbon bond, Yield and Double bond.

Kiyohiko Nakajima combines subjects such as Sulfoxide, Acetonitrile, Enantiomeric excess and Vanadium with his study of Schiff base. His Stereochemistry study frequently links to related topics such as Crystal structure. His Salicylaldehyde study deals with Pyridine intersecting with Ligand.

His most cited work include:

  • Preparation and characterization of optically active Schiff base-oxovanadium(IV) and -oxovanadium(V) complexes and catalytic properties of these complexes on asymmetric oxidation of sulfides into sulfoxides with organic hydroperoxides. (128 citations)
  • Crystal Structures of [VO(sal-L-ala)(OCH3)(CH3OH)] (sal-L-ala=N-salicylidene-L-alaninate) and {[VO(sal-L-ala)]2O}2·2CH2Cl2, and the Catalytic Activity of These and Related Complexes on Asymmetric Oxidation of Methyl Phenyl Sulfide with t-Butyl Hydroperoxide (119 citations)
  • Straightforward Method for Synthesis of Highly Alkyl-Substituted Naphthacene and Pentacene Derivatives by Homologation (117 citations)

What are the main themes of his work throughout his whole career to date?

His primary scientific interests are in Medicinal chemistry, Stereochemistry, Crystallography, Crystal structure and Ligand. His Medicinal chemistry research is multidisciplinary, incorporating perspectives in Organic chemistry, Ring, Catalysis and Palladium. His work in Stereochemistry addresses subjects such as Deprotonation, which are connected to disciplines such as Ruthenium and Coordination geometry.

His Crystallography research incorporates elements of Ethylenediamine and Diastereomer. The Crystal structure study combines topics in areas such as Proton NMR, Schiff base, Phosphine, Molecule and Amine gas treating. Within one scientific family, he focuses on topics pertaining to Enantiomeric excess under Schiff base, and may sometimes address concerns connected to Sulfoxide.

He most often published in these fields:

  • Medicinal chemistry (44.72%)
  • Stereochemistry (37.27%)
  • Crystallography (22.36%)

What were the highlights of his more recent work (between 2012-2021)?

  • Medicinal chemistry (44.72%)
  • Catalysis (19.25%)
  • Stereochemistry (37.27%)

In recent papers he was focusing on the following fields of study:

Kiyohiko Nakajima spends much of his time researching Medicinal chemistry, Catalysis, Stereochemistry, Palladium and Organic chemistry. His Medicinal chemistry study combines topics in areas such as Adduct, Ligand and Imine. His Catalysis research is multidisciplinary, relying on both Triple bond, Aryl and Yield.

His work on Wittig reaction as part of general Stereochemistry study is frequently linked to Ring-closing metathesis, bridging the gap between disciplines. The various areas that Kiyohiko Nakajima examines in his Palladium study include Denticity, Moiety, Lithium and C h bond. Kiyohiko Nakajima works on Organic chemistry which deals in particular with Coupling reaction.

Between 2012 and 2021, his most popular works were:

  • Palladium-Catalyzed peri-Selective Chalcogenation of Naphthylamines with Diaryl Disulfides and Diselenides via C–H Bond Cleavage (99 citations)
  • Chelate-Assisted Direct Selenation of Aryl C–H Bonds with Diselenides Catalyzed by Palladium (67 citations)
  • Iron‐Induced Regio‐ and Stereoselective Addition of Sulfenyl Chlorides to Alkynes by a Radical Pathway (45 citations)

In his most recent research, the most cited papers focused on:

  • Organic chemistry
  • Catalysis
  • Alkene

Kiyohiko Nakajima focuses on Stereochemistry, Catalysis, Medicinal chemistry, Organic chemistry and Palladium. His work deals with themes such as Allylic rearrangement and Enantioselective synthesis, which intersect with Stereochemistry. In his study, Triple bond, Adduct and Salt is inextricably linked to Yield, which falls within the broad field of Catalysis.

The Medicinal chemistry study which covers Imine that intersects with Pyridine, Quinoline, Linkage isomerism, Stereoisomerism and Ligand. His work on Aryl, Bond cleavage, Naphthylamine and C h bond is typically connected to Cleavage as part of general Organic chemistry study, connecting several disciplines of science. His study in Palladium is interdisciplinary in nature, drawing from both Aryne, Coupling reaction, Lewis acids and bases, Cationic polymerization and Coupling.
