Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Quantum mechanics
  • Catalysis

His primary scientific interests are in Catalysis, Organic chemistry, Stereochemistry, Medicinal chemistry and Rhodium. His research in the fields of Diastereomer overlaps with other disciplines such as Metallacycle. His studies in Medicinal chemistry integrate themes in fields like Phenylboronic acid, Triethylamine, Transition metal and Formic acid.

His work carried out in the field of Rhodium brings together such families of science as Hydroboration, Photochemistry and Reaction mechanism. His Ligand course of study focuses on Phosphine and Polymer chemistry. His studies deal with areas such as Combinatorial chemistry, Computational chemistry, Enantiomer and Isoquinoline as well as Enantioselective synthesis.

His most cited work include:

  • Rotational Spectroscopy of Diatomic Molecules (681 citations)
  • The labeling of parity doublet levels in linear molecules (676 citations)
  • Cellular differentiation hierarchies in normal and culture-adapted human embryonic stem cells (261 citations)

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

John M. Brown spends much of his time researching Atomic physics, Catalysis, Organic chemistry, Medicinal chemistry and Stereochemistry. John M. Brown has included themes like Hamiltonian, Laser and Nuclear magnetic resonance in his Atomic physics study. His Catalysis study incorporates themes from Combinatorial chemistry and Polymer chemistry.

His research on Medicinal chemistry often connects related topics like Phosphine. His research integrates issues of Crystallography, Ring and Ligand in his study of Stereochemistry. The concepts of his Rhodium study are interwoven with issues in Photochemistry and Asymmetric hydrogenation.

He most often published in these fields:

  • Atomic physics (22.79%)
  • Catalysis (22.13%)
  • Organic chemistry (18.20%)

What were the highlights of his more recent work (between 2005-2021)?

  • Catalysis (22.13%)
  • Organic chemistry (18.20%)
  • Atomic physics (22.79%)

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

John M. Brown mainly focuses on Catalysis, Organic chemistry, Atomic physics, Palladium and Medicinal chemistry. As a part of the same scientific family, he mostly works in the field of Catalysis, focusing on Combinatorial chemistry and, on occasion, Reagent. His Hydroboration, Regioselectivity and Rhodium study, which is part of a larger body of work in Organic chemistry, is frequently linked to Diene, bridging the gap between disciplines.

His biological study spans a wide range of topics, including Hamiltonian and Zeeman effect. He combines subjects such as Cationic polymerization and Alkene with his study of Palladium. His study on Enantioselective synthesis also encompasses disciplines like

  • Stereochemistry which connect with Electrophile and Reactivity,
  • Ligand which connect with Ruthenium and Phosphine.

Between 2005 and 2021, his most popular works were:

  • Palladium‐Catalyzed Allylic Fluorination (119 citations)
  • Transition‐Metal‐Mediated Reactions for C ? F Bond Construction: The State of Play (85 citations)
  • Palladium‐Catalyzed Substitution of Allylic Fluorides (71 citations)

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

  • Organic chemistry
  • Quantum mechanics
  • Catalysis

John M. Brown mostly deals with Catalysis, Organic chemistry, Medicinal chemistry, Enantioselective synthesis and Palladium. The Catalysis study combines topics in areas such as Combinatorial chemistry, Photochemistry, Phase and Hydrogen bond. His work on Urea as part of general Organic chemistry study is frequently connected to Diene, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them.

The various areas that John M. Brown examines in his Medicinal chemistry study include Stereochemistry and Nucleophile. John M. Brown works mostly in the field of Enantioselective synthesis, limiting it down to topics relating to Ring and, in certain cases, Salt, Chelation, Enantiomer, Atropisomer and Phosphine, as a part of the same area of interest. John M. Brown has researched Palladium in several fields, including Cationic polymerization, Alkene and Regioselectivity.
