The reaction of alkylidenephosphoranes with compounds containing halogens can be used to prepare ylides, which can be converted in to useful products, e.g. by hydrolysis, by thermal decomposition, or by other reactions. Examples of such products are ketones including cyclic, unsaturated, and branched‐chain ketones (including cyclic, unsaturated, and branched‐chain ketones), carboxlic esters (including those of unsaturated, branched‐ chain, polyenecarboxylic, acetylenecarboxylic, and allenecarboxylic acids), and aldehydes.
