Marcetta Darensbourg
Marcetta York Darensbourg (born May 4, 1942 in Artemus , Kentucky ) is an American chemist (inorganic chemistry and especially bioinorganic chemistry, organometallic chemistry, novel biologically inspired catalysts ).
Darensbourg graduated from Union College in Kentucky with a bachelor's degree in 1963 and received his PhD in inorganic chemistry in 1967 from Theodore L. Brown at the University of Illinois at Urbana-Champaign . The dissertation was on the kinetics of reactions of organic lithium compounds. Then she was Assistant Professor in inorganic chemistry at Vassar College , from 1969 Assistant Professor at the State University of New York at Buffalo and from 1971 Assistant Professor and later Professor at Tulane University . From 1982 she was Professor of Chemistry at Texas A&M University . There she is Distinguished Professor and holder of the Davidson Chair in Natural Sciences.
Darensbourg deals with reaction mechanisms in inorganic and organometallic chemistry, metal-mediated reactions at donor-ligand sites and molecular models of catalysts. She develops catalysts for bio-fuel cells using hydrogen. One goal is to replace expensive platinum with common elements such as iron, nickel and sulfur. Darensbourg uses the enzymatically active sites of biological iron-containing hydrogenases as a model.
She also looked at metal carbonyl complexes. From 2017, she investigated catalytically active complexes with metal dithiolates as ligands in different reactions (depending on the metal).
In 1981 she received the Agnes Fay Morgan Research Award and in 1998 the Southwest Region Award from the American Chemical Society (ACS). In 2013 she received the Fred Basolo Medal and in 2017 the American Chemical Society Award in Organometallic Chemistry . For 2019 she received the Willard Gibbs Medal . In 1989/90 she headed the Inorganic Chemistry Section of the American Chemical Society. She is a member of the National Academy of Sciences (2017) and the American Academy of Arts and Sciences (2011).
She has been married to chemistry professor Donald J. Darensbourg since 1967 , with whom she also published. Both received a professorship at Texas A&M University in 1982.
She is on the editorial board of Inorganic Syntheses .
