Synthesis of 1‐amino‐3‐aryl naphthalenes from bis(perfluoroalkanesulfonyl)imide with 1,2‐diethynylbenzenes

Although the synthesis of vinyl triflates has a long history, the synthesis of vinyl bis(perfluoroalkanesulfonyl)imides has not been reported yet. Here, we report a simple synthetic route to vinyl bis(perfluoroalkanesulfonyl)imides that does not require any additives. The stereoselectivity originates from the steric hindrance between the aryl group and the imide. The reaction proceeds chemoselectively, and subsequent cyclization provides the 1‐amino‐3‐aryl naphthalene derivatives.
