Robert George Bergman is an American chemist. He is Professor of the Graduate School and Gerald E. K. Branch Distinguished Professor Emeritus at the University of California, Berkeley.[1]
Bergman began his independent career at the California Institute of Technology in Pasadena where he was an Arthur Noyes Research Instructor (1967–1969), assistant professor (1969–1971), associate professor (1971–1973), and full professor (1973–1977).[2] From 1977 to 2002, he was a chemistry professor at the University of California, Berkeley and since 1978 has also been a researcher at the Lawrence Berkeley National Laboratory. In 2002 he was appointed Gerald E. K. Branch Distinguished Professor of Chemistry. Bergman transitioned to Emeritus status in 2016 and now holds to the titles of Professor of the Graduate School and Gerald E. K. Branch Distinguished Professor Emeritus.[1]
Research
Bergman works in the field of organic chemistry. He first investigated the reaction mechanisms of organic reactions at Caltech. He developed methods for the representation of very reactive molecules, for example 1,3-diradicals and vinyl cations. In 1972, he discovered the thermal cyclization of cis-1,5-hexadiyne-3-ene to 1,4-dehydrobenzene-diradicals, now known as the Bergman cyclization.[3][4] This reaction later played a major role in understanding the mode of action of enediyne antitumor antibiotics.[5][6] Since the mid-1970s, Bergman has also been working in the field of organometallic chemistry.[7] He contributed to the synthesis and reaction of organometallic complexes and investigated organometallic compounds with metal-oxygen and metal-nitrogen bonds. He also discovered the first soluble organometallic complexes of the transition metals, to which the addition of a saturated hydrocarbon (C-H activation, C-H insertion) succeeded.[8][9]
Personal life
Since June 17, 1965, Bergman has been married. The Bergmans have two sons.[citation needed]
