DMF as a hydride source via a Pd‐catalyzed reaction and switching to CH3CN solvent, an efficient route for the synthesis of emeraldicene and some new substituted derivatives is reported with potential application in organic electronics. Additionally, the nucleophilic alkylation of emeraldicene 4 a with alkyllithium reagents provides monosubstituted compounds 7 a and 7 b, the latter crystallizing in columnar
