Gregory H. Robinson FRSC is an American synthetic inorganic chemist and a Foundation Distinguished Professor of Chemistry at the University of Georgia. Robinson's research focuses on unusual bonding motifs and low oxidation state chemistry of molecules containing main group elements such as boron, gallium, germanium, phosphorus, magnesium, and silicon. He has published over 150 research articles, and was elected to the National Academy of Sciences in 2021.

Education

Robinson received his B.S. from Jacksonville State University (1980) and his Ph.D. from the University of Alabama (1984).[1] [2] He joined the faculty at the University of Georgia in 1995.

Discoveries

Robinson has made a number of seminal discoveries in the field of synthetic inorganic chemistry. Many of these discoveries have concerned unusual molecules involving the main group elements.

Aromatic molecules constitute a particularly important class of organic compounds. In general, aromatic molecules contain planar carbon-based cyclic ring systems. In addition, aromatic molecules also possess enhanced stability due to electron delocalization. The iconic aromatic molecule is benzene, C6H6. Inherent in the traditional concept of aromaticity, is the fact that metals were considered incapable of displaying traditional aromatic behavior. Robinson discovered that the main group metal gallium, if properly constrained, could exhibit aromatic behavior.[3]

This [R<sub>3</sub>Ga<sub>3</sub>]2- dianion was found to be isoelectronic with the aromatic triphenylcyclopropenium cation, [Ph<sub>3</sub>C<sub>3</sub>]+. Thus, the concept of “metalloaromaticity”, the proposition that a metallic ring system could display traditional aromatic behavior historically restricted to carbon ring systems (i.e., benzene), was experimentally realized.[3]

    The chemistry of boron, the fifth element on the Periodic Table, is as rich as it is varied. However, boron had not been shown to engage in robust multiple bonding like its periodic neighbor carbon. Robinson utilized a class of organic bases known as carbenes (L:) to prepare the first neutral compound containing a boron-boron double bond, the first diborene, with the synthesis and molecular structure of L:(H)B=B(H):L.[4] [5] The chemistry of molecules containing boron-boron multiple bonds is now a thriving area of research.

    Robinson utilized a similar technique to prepare a highly unusual compounds containing a silicon-silicon double bond, with both silicon atoms residing in the formal oxidation state of zero, L:Si=Si:L. Essentially, this compound represented a means to stabilize the highly reactive diatomic allotropes of silicon at room temperature. Since this discovery, several other molecules have subsequently been prepared including diphosphorus.[6] [7] [8]
