Total Synthesis of Functionalized Acenes
Research project focused on preparation of acene dinitriles from benzene 1,2-dicarbaldehyde. A Wittig reagent of fumaronitrile and triethylphosphine yielded a new C-C double. The increased acidity of the a-H, between the new alkene bond and a cyano group, allowed an Aldol reaction to take place and resulted in a ring closure. Condensation reaction established aromaticity in the new ring, carrying dicyano functionality. To allow additional ring formations via reaction sequence repetitions, nitrile groups were reduced with DIBALH to dialdehydes.
