Pericyclic Reactions Part 3: Sigmatropic Shifts (Cope Rearrangement, Claisen Rearrangement)
Now that we have sufficiently covered cycloaddition reactions, we can move on to the next type of pericyclic reactions. That would be sigmatropic shifts. This includes important synthetic techniques like the Cope rearrangement, Oxy-Cope...

Peterson Olefination
Next in the series of olefination reactions is the Peterson olefination. This uses alpha-halo silanes and is quite fascinating, with a number of unique advantages. Namely, the stereochemistry of the alkene product can be controlled by...
