The allyl ester of a carboxylic acid is used instead of an allyl vinyl ether in the Ireland modification of this man's namesake [3,3]-sigmatropic rearrangement.  One form of another reaction named after this man has high yield only if one of the reactants has no alpha hydrogen, that being the "crossed" version, and another form of that reaction competes with cleavage via ring scission and is named after Dieckmann.  That reaction produces a beta-ketoester from two esters in basic solution.  For 1
