SUMMARY:Helen Murray Free Endowed Technical Lecture
DESCRIPTION:Gregory Robinson\, PhD\n\n\n\nFoundation Distinguished Professor of Chemistry\, University of Georgia \n\n\n\nLocation: Ruth W. Williams Hall of Life Sciences\, Room 060 \n\n\n\n\n\nTechnical Lecture\n\n\n\n\n\n\n\nN-Heterocyclic Carbenes and Dithiolene Radicals: Counterintuitive Main Group Chemistry \n\n\n\nOur laboratory has long pursued the synthesis\, structure\, and reactivity of unusual molecules that prominently feature main group elements. These efforts resulted in several significant milestones including the experimental realization of “metalloaromaticity” (the concept that metallic rings may also display traditional aromatic behavior as exhibited by benzene)\, synthesis of the first molecule containing a boron-boron double bond—the first “diborene”\, and synthesis of the first molecule containing a triple bond between two main group metals (the gallium analog of acetylene). Research efforts have also concerned carbene stabilization of highly reactive main group molecules such diphosphorus (P2)\, diarsenic (As2)\, and disilicon (Si2). This presentation will prominently feature our efforts to synthetically augment the molecular template of N-heterocyclic carbenes and their surprising conversion to stable dithiolene-based chemical radicals\, which have shown promise in the activation of small molecules\, such as ammonia. \n\n\n\nLearn more about Professor Robinson: https://www.gregoryhrobinson.com/ \n\n\n\nSelected Awards: \n\n\n\n\nAmerican Academy of Arts and Sciences (elected in 2025)\n\n\n\nNational Academy of Sciences (elected 2021)\n\n\n\nFellow of the Royal Society of Chemistry (2017)\n\n\n\nF.

SUMMARY:Helen Murray Free Endowed Public Lecture
DESCRIPTION:Gregory Robinson\, PhD\n\n\n\nFoundation Distinguished Professor of Chemistry\, University of Georgia\n\n\n\n\n\nRuth W. Williams Hall of Life Sciences\, Room 060 \n\n\n\nPublic Lecture: \n\n\n\n\n\n\n\nFrom Hydrogen to Radon: Playing the ‘Long Game’ in Inorganic Chemistry \n\n\n\nFrom the syntheses of the first molecules containing boron-boron double bonds—the first “diborenes”—to the first molecule shown to possess a triple bond between two main group metals—the first “gallyne”—a digallium analog of acetylene\, the Robinson Laboratory has made noteworthy contributions to Inorganic Chemistry. Consequently\, in addressing foundational issues of structure and bonding\, fascinating new areas of chemistry have emerged from the Robinson laboratory such as metalloaromaticity (the realization that properly constrained metallic ring systems can display traditional aromatic properties\, thereby mimicking the chemical behavior of benzene)\, multiple-bonding involving heavier main group elements\, stabilization of silicon dioxide-based precursors to “molecular sand”\, dithiolene-based aluminum tri-radicals. These discoveries will be summarized and placed in historical context. As history can attest\, “change” is frequently disruptive.   \n\n\n\n\n\n\n\nLearn more about Professor Robinson: https://www.gregoryhrobinson.com/ \n\n\n\nReception\, sponsored by the Wooster Local Section of the American Chemical Society\, follows the lecture. \n\n\n\nSelected Awards: \n\n\n\n \n\n\n\n\nAmerican Academy of Arts and Sciences (elected in 2025)\n\n\n\nNational Academy of Sciences (elected 2021)\n\n\n\nFellow of the Royal Society of Chemistry (2017)\n\n\n\nF.
