Abstract :
The reactivity of the cyanine dyes towards nucleophilic reagents is currently being tested. As in the case of phosphine derivatives, carbanions attack the electrophilic C3 carbon of the pentamethine chain to give, with a good yield, new functionalized podands with cyano, keto, amino, amido, or enol-ether moieties.
