Meagan Evans receives Best Presentation at the 41st Annual Inorganic Discussion Weekend, Brock University


Meagan Evans, a third year graduate student in the Jones Group, received the "best presentation" award at Brock University's 41st Annual Inorganic Discussion Weekend which took place from Nov. 28 - Nov. 30, 2008 in St. Catharines, Canada. Meagan was recognized for her work on C-H bond activation of fluorinated aromatic hydrocarbons by [Tp`Rh(CN-neopentyl)] which is used to determine the stability of the Rh-Caryl bond and proves to be strongly dependent on the number of ortho fluorines. Competition experiments along with ΔGre≠ values allowed for the determination of relative Rh-Caryl bond strengths and illustrate the large ortho fluorine effect. A plot of M-C bond strength vs. C-H bond strength resulted in a trend-line that matches theoretical predictions within 3%.
