We pay particular attention to the types of\nligands, reagents, and methods that have become popular during the past decade, and contextualize them within the\nbroad fields of organometallic and inorganic chemistry more generally. The chapter, which is necessarily limited in\nscope, discusses a range of varied topics including the use of steric bulk in small molecule activation, reversibly\ncyclometallated species, highly electrophilic organometallics and their corresponding non-coordinating anions, zwitterionic\norganometallic species, carbene ligands, secondary coordination sphere interactions, fluorous phases, and\nC atom transfer reagents in organometallic synthesis. Many of the reagents, ligands, and methods employed in these\nvarious areas of synthesis are described, and many relevant references are provided.", } @book_section {CaltechAUTHORS_https://authors.library.caltech.edu/id/eprint/27268, title ="Bio-organometallic Approaches to Nitrogen Fixation Chemistry", author = "Peters, Jonas C. and Mehn, Mark P.", pages = "81-119", month = "January", year = "2006", isbn = "9783527313129", url = "https://resolver.caltech.edu/CaltechAUTHORS:20111018-082532542", note = "© 2006 Wiley-VCH.

As such, nitrogen fixation is essential to sustaining life on this planet, and has attracted intense scrutiny among biological and chemical communities for decades [2-4]. The mechanism by which nitrogenase enzymes promote the biological reduction of nitrogen under ambient conditions remains an unsolved\nand fascinating problem [4-6]. Nature's solution to fixing nitrogen stands in sharp contrast to that which humanity has adopted, i.e. the Haber-Bosch process for ammonia synthesis that is carried out at approximately 200 atm and\n500°C. This Herculean feat of chemical engineering provides, in net, about 50% of the nitrogen atoms that wind up in all human beings on this planet [7]. From a chemists perspective, however, this remains a brute force and high-energy solution to the nitrogen fixation problem, especially given the knowledge that nature can fix N_2 under ambient conditions.", } @book_section {CaltechAUTHORS_https://authors.library.caltech.edu/id/eprint/27269, title ="Issues Relevant to C-H Activation at Platinum(II): Comparative Studies between Cationic, Zwitterionic, and Neutral Platinum(II) Compounds in Benzene Solution", author = "Peters, Jonas C. and Thomas, J.
