摘要

PtCl2 (5 mol%) is an effective catalyst for aromatization of enediynes via a CH bond insertion of tethered alkanes. The reaction mechanism of this cyclization is proposed to involve platinum-π-alkyne intermediates. This cyclization works not only for terminal alkynes but also for internal alkynes.
