Polyethylene glycol, or PEG, is used to promote the formation of them, and they can be incorporated into heterocyclic systems: for example, the meso- ionic sydnone molecule contains an azomethine imine one.

The Corey-Fuchs reaction forms one (*) as an intermediate from carbon tetrabromide, after which it is added to an aldehyde to form a dibromoalkene. Sulfur-containing ones are called pi-sulfuranes, and they are prepared by deprotonation of sulfonium salts by alkylation with an alkyl halide. FTP, name these compounds which have two adjacent atoms with full octets of electrons and formal positive and negative charges, one of which can be generated from a phosphonium salt and reacted with an aldehyde or ketone to form an alkene in the Wittig Reaction.
