Reaction mechanisms: pericyclic reactions

This review summarizes a number of articles published in 2011 describing mechanisms of pericyclic reactions. The types of reactions studied were of the cycloaddition sort (e.g., [2+1], [2+2], [3+2], [4+2], etc.), as well as sigmatropic (e.g., [1,2], [1,3], [3,3] shifts, etc.), group transfer (e.g., ene), and electrocyclic types. Interestingly, the literature on pericyclic cascade reactions was quite rich in 2011.
