Parallel synthesis of strongly fluorescent polysubstituted 2,6-dicyanoanilines via microwave-promoted multicomponent reaction.

[reaction: see text] A facile parallel synthesis of polysubstituted 2,6-dicyanoanilines via microwave-promoted three-component reaction of aldehydes, ketones, and propanedinitrile in solution and also on polymer support has been developed. The screening for optical properties identified two new compounds with high fluorescence quantum yields.
