Maining 32 solvents, we acquired an l/m ratio of 2.76 for four, which was found to become quite close for the two.88 value for 1 in identical solvents. This supports our proposal that the tetrahedral carbonyl-addition transition-state 4 is analogous to that of 1. The log (k/ko) plot of 5 against 1 was close to excellent, with an r2 value of 0.991, in addition to a slope that was slightly higher than unity. The equivalent l/m ratios for 5 and 1 verified that the two substrates had practically indistinguishable tetrahedral transition-state structure.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptAcknowledgmentsResearch reported in this peer-reviewed post was supported by an Institutional Improvement Award (Concept) in the National Institute of Basic Medical Sciences in the National Institutes of Overall health (NIGMS-NIH) below grant number P20GM103446-13 (DE-INBRE grant); the National Science Foundation (NSF) EPSCoR Grant No. IIA-1301765 (DE-EPSCoR); the State of Delaware; and an NSF ARI-R2 grant 0960503.
