And, exp(-ΔG/RT) = k1/k-1, so there’s really only one thing. Kinetics provides information about the transition state of a reaction. We’ll use a simple example to lear… Protecting Groups in Organix Synthesis - Ready Lab - UT Southwestern, Dallas, Texas https://labs.utsouthwestern.edu/sites/default/files/2022-08/protecting-groups.pdf Protecting Groups in Organic Synthesis-1 Ready Protecting groups are a sad fact of synthetic chemistry They are usually needed, but rarely desired Many syntheses have stalled because of trouble putting on or removing protecting groups 4 bas… Oxidations to Carbonyl - Ready Lab - UT Southwestern, Dallas, Texas https://labs.utsouthwestern.edu/sites/default/files/2022-08/oxidations-to-carbonyl.pdf Oxidations at Carbon General references March, Advanced Org Chem, 1992, 1158-1238 Trost, Comp.
