In the first project, an iron complex with a bulky tetradentate ligand is used to guide the regioselectivity of catalyzed C-H activation away from the thermodynamically weakest bonds in alkane substrates. An additional benefit provided by the ligand is that it allows the study of reactive intermediates in the catalyzed oxidation of C-H bonds by O\u003Csub\u003E2\u003C\/sub\u003E. In the second project, a redox-active ligand is used to prepare a manganese-containing MRI contrast agent that is capable of detecting H\u003Csub\u003E2\u003C\/sub\u003EO\u003Csub\u003E2\u003C\/sub\u003E under physiologically relevant conditions. The reaction with H\u003Csub\u003E2\u003C\/sub\u003EO\u003Csub\u003E2\u003C\/sub\u003E couples the mononuclear contrast agent into a binuclear species that is less paramagnetic per Mn(II) ion, reducing the overall relaxivity.\u003C\/p\u003E\u003Cp\u003EFor more information contact \u003Ca href=\u0022mailto:jake.soper@chemistry.gatech.edu\u0022\u003EProf. Jake Soper\u003C\/a\u003E (404-894-4022).\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EProf. Christian Goldsmith, Auburn University\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003E\u003Cstrong\u003EDesigning Coordination Compounds to Tune the Regioselectivity of Alkane Oxidation and Directly Sense Reactive Oxygen Species by MRI\u003C\/strong\u003E\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003EInorganic Chemistry Serminar Series\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":"","uid":"27275","created_gmt":"2012-07-17 13:59:59","changed_gmt":"2016-10-08 01:59:16","author":"Shirley Tomes","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2012-09-25T17:00:00-04:00","event_time_end":"2012-09-25T18:00:00-04:00","event_time_end_last":"2012-09-25T18:00:00-04:00","gmt_time_start":"2012-09-25 21:00:00","gmt_time_end":"2012-09-25 22:00:00","gmt_time_end_last":"2012-09-25 22:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"140791":{"id":"140791","type":"image","title":"Goldsmith 1","body":null,"created":"1449178710","gmt_created":"2015-12-03 21:38:30","changed":"1475894771","gmt_changed":"2016-10-08 02:46:11","alt":"Goldsmith 1","file":{"fid":"194925","name":"goldsmith1.jpg","image_path":"\/sites\/default\/files\/images\/goldsmith1_0.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/goldsmith1_0.jpg","mime":"image\/jpeg","size":47611,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/goldsmith1_0.jpg?itok=UQwBKxor"}},"140801":{"id":"140801","type":"image","title":"Goldsmith 2","body":null,"created":"1449178710","gmt_created":"2015-12-03 21:38:30","changed":"1475894771","gmt_changed":"2016-10-08 02:46:11","alt":"Goldsmith 2","file":{"fid":"194926","name":"goldsmith2.jpg","image_path":"\/sites\/default\/files\/images\/goldsmith2_0.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/goldsmith2_0.jpg","mime":"image\/jpeg","size":38826,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/goldsmith2_0.jpg?itok=b8wCxq69"}}},"media_ids":["140791","140801"],"related_links":[{"url":"http:\/\/www.auburn.edu\/academic\/cosam\/faculty\/chemistry\/goldsmith\/research\/","title":"Prof. Christian R.
