Cost and toxicity concerns have spurred efforts to replace the precious metals in coupling catalysts with Earth-abundant later first-row metals. Because these metal ions typically exist in oxidation states that vary by only one electron, they are often prone to radical reactions with organic substrates. We have addressed this issue by exploiting the capacity of \u0022non-innocent\u0022 redox-active ligands to store and deliver charge for selective two-electron organometallic bond-making and breaking reactions at naturally abundant metal ions. This seminar will present our recent successes in elaborating base metal complexes for palladium-like C\u00e2\u0080\u0022C coupling cycles, including cobalt-catalyzed cross coupling of unactivated alkyl halides with organic nucleophiles and manganese-catalyzed aerobic oxidative homocoupling of alkyl-, alkenyl-, alkynl-, and aryl-carbanions.\n\u003C\/p\u003E\n\u003Cp\u003EFor more information contact \u003Ca href=\u0022mailto:charles.liotta@chemistry.gatech.edu\u0022\u003EProf. Charles Liotta\u003C\/a\u003E (404-894-8222).\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Prof. Jake Soper, Georgia Tech\n\nAlmost Alchemy: Radical Ligands Facilitate Palladium-Like Coupling Reactions at Manganese, Iron and Cobalt","format":"limited_html"}],"field_summary_sentence":[{"value":"Prof. Jake Soper, Georgia Tech"}],"uid":"27275","created_gmt":"2010-01-07 01:00:00","changed_gmt":"2016-10-08 01:48:43","author":"Shirley Tomes","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2010-09-09T17:00:00-04:00","event_time_end":"2010-09-09T18:00:00-04:00","event_time_end_last":"2010-09-09T18:00:00-04:00","gmt_time_start":"2010-09-09 21:00:00","gmt_time_end":"2010-09-09 22:00:00","gmt_time_end_last":"2010-09-09 22:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www.chemistry.gatech.edu\/faculty\/Soper\/","title":"Prof. Jake Soper, Georgia Tech"}],"groups":[{"id":"85951","name":"School of Chemistry and Biochemistry"}],"categories":[],"keywords":[{"id":"89","name":"chemistry"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EShirley Tomes\u003C\/strong\u003E\u003Cbr \/\u003EChemistry \u0026amp; Biochemistry\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=st81\u0022\u003EContact Shirley Tomes\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-0591\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
