Notably, there is a widespread perception that the formation of commonly encountered metal alkoxide species results from the auto\u2010oxidation reaction, in which a parent metal alkyl compound is oxidized by the metal alkylperoxide via oxygen transfer reaction. Now, harnessing a well\u2010defined zinc ethylperoxide incorporating a \u03b2\u2010diketiminate ligand, the investigated alkylperoxide compounds do not react with the parent metal alkyl complex as well as Et2Zn to form a zinc alkoxide. Upon treatment of the zinc ethylperoxide with Et2Zn, a previously unobserved ligand exchange process is favored. Isolation of a zinc hydroxide carboxylate as a product of decomposition of the parent zinc ethylperoxide demonstrates the susceptibility of the latter to O\u2212O bond homolysis.<\/p>\n<p><a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/full\/10.1002\/anie.201904380\" target=\"_blank\" rel=\"noopener noreferrer\">Paper on the Publisher's website<\/a><\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" class=\"aligncenter  wp-image-2004\" alt=\"chemsci2019tempo\" src=\"wp-content\/uploads\/2019\/07\/anie2019o2.jpg\" width=\"670\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Angewandte Chemie International Edition, 2019, 58, 8526\u20138530. &nbsp; An In\u2010Depth Look at the Reactivity of Non\u2010Redox\u2010Metal Alkylperoxides Tomasz Pietrzak,a Iwona Justyniak,b Marcin Kubisiak,a Emil Bojarski,a Janusz Lewi\u0144ski*ab a&nbsp;Faculty of Chemistry, Warsaw University of Technology, Noakowskiego 3, 00-664 Warsaw, Poland b&nbsp;Institute of Physical Chemistry, Polish Academy of Sciences, Kasprzaka 44\/52, 01-224 Warsaw, Poland DOI: 10.1002\/anie.201904380.
