John Hartwig
John F. Hartwig is an American organometallic chemist who holds the position of Henry Rapoport Professor of Chemistry at the University of California, Berkeley. His laboratory traditionally focuses on developing transition metal-catalyzed reactions. Hartwig is known for helping develop the Buchwald–Hartwig amination, a chemical reaction used in organic chemistry for the synthesis of carbon–nitrogen bonds via the palladium-catalyzed cross-coupling of amines with aryl halides. Education and training Hartwig received his A.B. from Princeton University in 1986. With Robert G. Bergman and Richard A. Andersen as coadvisors, he earned his Ph.D. from the University of California, Berkeley in 1990. Thereafter he was an American Cancer Society Postdoctoral Associate at MIT, where he worked in the laboratory of Stephen J. Lippard. Research He assumed an independent position at Yale University in 1992. Over the next 14 years, he was promoted to associate professor, full profes ...

Elmhurst, Illinois
Elmhurst is a city in DuPage County, Illinois, DuPage and Cook County, Illinois, Cook counties in the U.S. state of Illinois. It is a western suburb of Chicago. The population was 45,786 at the 2020 United States census, 2020 census. History Members of the Potawatomi Native Americans in the United States, Native American people, who settled along Salt Creek (Des Plaines River tributary), Salt Creek just south of where the city would develop, are the earliest known settlers of the Elmhurst area. Around 1836, European-American immigration, immigrants settled on tracts of land along the same stream, creek. At what would become Elmhurst City Centre, a native of Ohio named Gerry Bates established a community on a tract of "treeless land" in 1842. The following year, Hill Cottage Tavern opened where St. Charles Road and Cottage Hill Avenue presently intersect. In 1845, the community was officially named Cottage Hill when a post office was established. Four years later, the Galena an ...

Palladium-catalyzed Cross-coupling
In organic chemistry, a cross-coupling reaction is a reaction where two different fragments are joined. Cross-couplings are a subset of the more general coupling reactions. Often cross-coupling reactions require metal catalysts. One important reaction type is this: : (R, R' = organic fragments, usually aryl; M = main group center such as Li or MgX; X = halide) These reactions are used to form carbon–carbon bonds but also carbon-heteroatom bonds. Cross-coupling reaction are a subset of coupling reactions. Richard F. Heck, Ei-ichi Negishi, and Akira Suzuki were awarded the 2010 Nobel Prize in Chemistry for developing palladium-catalyzed coupling reactions. Mechanism Many mechanisms exist reflecting the myriad types of cross-couplings, including those that do not require metal catalysts. Often, however, cross-coupling refers to a metal-catalyzed reaction of a nucleophilic partner with an electrophilic partner. In such cases, the mechanism generally involves reductive eliminat ...

American Academy Of Arts And Sciences
The American Academy of Arts and Sciences (The Academy) is one of the oldest learned societies in the United States. It was founded in 1780 during the American Revolution by John Adams, John Hancock, James Bowdoin, Andrew Oliver, and other Founding Fathers of the United States. It is headquartered in Cambridge, Massachusetts. Membership in the academy is achieved through a nominating petition, review, and election process. The academy's quarterly journal, '' Dædalus'', is published by the MIT Press on behalf of the academy, and has been open-access since January 2021. The academy also conducts multidisciplinary public policy research. Laurie L. Patton has served as President of the Academy since January 2025. History The Academy was established by the Massachusetts legislature on May 4, 1780, charted in order "to cultivate every art and science which may tend to advance the interest, honor, dignity, and happiness of a free, independent, and virtuous people."

Clarivate Citation Laureates
Clarivate Citation Laureates, formerly Thomson Reuters Citation Laureates, is a list of candidates considered likely to win the Nobel Prize in their respective field. The candidates are so named based on the citation impact of their published research.The list of awardees is announced annually prior to the Nobel Prize ceremonies of that year. In October 2016, Thomson Reuters Intellectual Property and Science Business was acquired by Onex and Baring Asia and the newly independent company was named as Clarivate. Thomson Reuters Citation Laureates was established in 1989. The list pertains to likely Nobel Prize winners in medicine, chemistry, physics, and economics. There appears to be a correlation between high citation rates for a published researcher and the award of prestigious accolades. Furthermore, citation rates disclose researchers furnishing instrumental contributions that advance the science of their respective field. Finally, choosing one tenth of one percent (0.1%) of th ...

Emanuel Merck Lectureship
The Emanuel Merck Lectureship was founded in 1992 by Technische Universität Darmstadt and Merck KGaA located in Darmstadt, Germany. The lectureship aspires to enlighten scientists and students at Technische Universität Darmstadt, as well as Merck KGaA employees and interested public with leading scientific research in chemistry. The award honors Heinrich Emanuel Merck (1794–1855) the founder of Merck, an entrepreneur, an original experimenter and a successful scientist. Emanuel Merck maintained membership in many scientific associations and held many personal relationships with leading researchers of his era, including Justus von Liebig, Friedrich Wöhler, Max von Pettenkofer and Louis Pasteur. The Emanuel Merck Lectureship attempts to continue this tradition of international exchange between researchers. The lectures are held over multiple days. The lectures include lectures that are open to the public, lectures for a closed audience and seminars for students. The invitation ...
