This family of well-defined compounds was examined as a model system for the activation of dioxygen mediated by using complexes that feature lack of a redox-active metal center. Experimental and theoretical studies indicate an essential role in the oxygenation process of intramolecular interactions that involve aromatic subunits. Additionally, novel results for the oxygenation chemistry of alkylzinc compounds, including the isolation and structural characterization of the unique octanuclear aryloxide (hydroxide) compound Zn<sub>8<\/sub>(OAr)<sub>8<\/sub>(OH)<sub>6<\/sub>(O<sub>2<\/sub>) with an encapsulated peroxide species, are presented.\n<\/td>\n<td>\n<img decoding=\"async\" src=\"http:\/\/lewin.ch.pw.edu.pl\/wp-content\/uploads\/2014\/11\/chej2014pi.png\" alt=\"chej2014pi\" width=\"160\" \/>\n<\/td>\n<\/tr>\n<\/table>\n<p><a href=\"http:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/chem.201403851\/abstract\" target=\"_blank\">Paper on the Publisher's website<\/a><br \/>\n<a href=\"wp-content\/uploads\/2014\/09\/chej2014pi.pdf\" target=\"_blank\">Full-text PDF<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Chemistry &#8211; a European Journal, 2014, 20, 5093\u20135096. &nbsp; Probing the Role of \u03c0 Interactions in the Reactivity of Oxygen Species: A Case of Ethylzinc Aryloxides with Different Dispositions of Aromatic Rings Toward the Metal Center \u0141ukasz M\u0105kolski,a Karolina Zelga,a Rafa\u0142 Petrus,b Dominik Kubicki,a Piotr Zarzycki,c Piotr Sobota,*b Janusz Lewi\u0144ski*ac a Faculty of Chemistry, Warsaw [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":3185,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[19],"tags":[],"class_list":["post-3175","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-paper"],"_links":{"self":[{"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/posts\/3175","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=3175"}],"version-history":[{"count":20,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/posts\/3175\/revisions"}],"predecessor-version":[{"id":3274,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/posts\/3175\/revisions\/3274"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/media\/3185"}],"wp:attachment":[{"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3175"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3175"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3175"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
