The synthesis of a new extended π-conjugated 5-N, N-dimethylaminonaphthyl family was undertaken by palladium-catalyzed cross-coupling reaction between a protected 5- iodonaphthylethynyl and 1-ethynyl-5-(N, N-dimethylamino) naphthalene. Under an argon atmosphere, only the homocoupling product 1, 4-(N, N-dimethylamino) naphthyl-1, 3- butadiyne was isolated, in excellent yield. However, under a compatible and pure carbon ...
