Abstract

Indigo di- and monoimines can be protonated to form stable salts in which the central C[double bond, length as m-dash]C bond has isomerized from a trans to cis configuration. Deprotonation of these salts regenerates the neutral trans species. The protonation chemistry of indigo is also explored.
