Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Catalysis
  • Alkene

His primary areas of study are Catalysis, Organic chemistry, Medicinal chemistry, Asymmetric hydrogenation and Enantioselective synthesis. His work deals with themes such as Combinatorial chemistry, Zinc and Polymer chemistry, which intersect with Catalysis. His Allylic rearrangement, Alkyl, Amination and Yield study, which is part of a larger body of work in Organic chemistry, is frequently linked to Zinc Cluster, bridging the gap between disciplines.

Kazushi Mashima has included themes like Cationic polymerization, Toluene, Ligand and Ruthenium in his Medicinal chemistry study. His Asymmetric hydrogenation research integrates issues from Enantiomeric excess, Stereochemistry, Noyori asymmetric hydrogenation and BINAP. As a member of one scientific family, Kazushi Mashima mostly works in the field of Enantioselective synthesis, focusing on Alkynylation and, on occasion, Substrate and Chemoselectivity.

His most cited work include:

  • Practical synthesis of (R)- or (S)-2,2'-bis(diarylphosphino)-1,1'-binaphthyls (BINAPs) (281 citations)
  • Cationic BINAP-Ru(II) Halide Complexes: Highly Efficient Catalysts for Stereoselective Asymmetric Hydrogenation of .alpha.- and .beta.-Functionalized Ketones (246 citations)
  • 1,3-Diene complexes of zirconium and hafnium prepared by the reaction of enediylmagnesium with MCl2Cp2. A remarkable difference between the zirconium and hafnium analogs as revealed by proton NMR and electronic spectra (134 citations)

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

Kazushi Mashima spends much of his time researching Catalysis, Medicinal chemistry, Organic chemistry, Polymer chemistry and Stereochemistry. Many of his research projects under Catalysis are closely connected to Zinc Cluster with Zinc Cluster, tying the diverse disciplines of science together. His research in Medicinal chemistry intersects with topics in Ruthenium, Moiety, Ligand, Metal and Cationic polymerization.

His Ligand research is multidisciplinary, incorporating perspectives in Inorganic chemistry and Photochemistry. His research integrates issues of Lanthanide, Ethylene, Polymerization and Tantalum in his study of Polymer chemistry. His research in Stereochemistry tackles topics such as Crystal structure which are related to areas like X-ray crystallography.

He most often published in these fields:

  • Catalysis (47.60%)
  • Medicinal chemistry (35.47%)
  • Organic chemistry (32.49%)

What were the highlights of his more recent work (between 2013-2021)?

  • Catalysis (47.60%)
  • Medicinal chemistry (35.47%)
  • Organic chemistry (32.49%)

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

Kazushi Mashima mostly deals with Catalysis, Medicinal chemistry, Organic chemistry, Polymer chemistry and Ligand. Asymmetric hydrogenation, Reaction mechanism, Alkyne, Rhodium and Enantioselective synthesis are the subjects of his Catalysis studies. Kazushi Mashima works mostly in the field of Asymmetric hydrogenation, limiting it down to concerns involving Iridium and, occasionally, Halide.

The concepts of his Medicinal chemistry study are interwoven with issues in Intramolecular force, Stereochemistry, Moiety and Reactivity. His biological study spans a wide range of topics, including Carboxylate, Manganese and Lanthanide. His research in Ligand tackles topics such as Catalytic cycle which are related to areas like Cerium.

Between 2013 and 2021, his most popular works were:

  • Magnesium hydridotriphenylborate [Mg(thf)6][HBPh3]2: a versatile hydroboration catalyst (101 citations)
  • 1,4-Bis(trimethylsilyl)-1,4-diaza-2,5-cyclohexadienes as Strong Salt-Free Reductants for Generating Low-Valent Early Transition Metals with Electron-Donating Ligands (74 citations)
  • Asymmetric Allylic Alkylation of β‐Ketoesters with Allylic Alcohols by a Nickel/Diphosphine Catalyst (45 citations)

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

  • Organic chemistry
  • Catalysis
  • Alkene

Kazushi Mashima mainly focuses on Catalysis, Medicinal chemistry, Organic chemistry, Trimethylsilyl and Ligand. His work on Catalysis is being expanded to include thematically relevant topics such as Polymer chemistry. His Medicinal chemistry research includes elements of Reagent, Reactivity, Bond cleavage and Alkyne.

The study incorporates disciplines such as Stereochemistry and Metathesis in addition to Reactivity. His Trimethylsilyl research incorporates elements of Inorganic chemistry, Aryl and Multiple bonds. His Ligand research is multidisciplinary, incorporating elements of Photochemistry, Adduct, Benzoic acid and Cerium.
