Input (English): When one reaction by this name takes place between ketenes and a cyclic system, it is named for Bellus, and its Eschenmoser modification is used to create amides. A combination of that reaction with the Staudinger ligation is referred to as the Chen-Mapp reaction, while a version of it with allylic acetates that creates carboxylic acids is called the Ireland modification. Another reaction with this name has a crossed version that is useful when only one of the reactants has an enolizable alpha hydrogen. That reaction has an intermolecular version named for Dieckmann. FTP, name these two reactions, one of which takes an allyl vinyl ether to a delta-gamma unsaturated carbonyl by rearrangement and the other of which produces a beta-ketoester from the condensation of two esters.
