Abstract

Phosphorus-embedded porous organic polymers (P-POPs) play a vital role in catalysis and sustainable chemical synthesis. This study uses an olefin-linked P-POP to stabilize Pd nanoparticles that catalyze Larock’s annulation to synthesize symmetrical indenones in high yields. Unsymmetric indenones were obtained with exclusive regioselectivities by employing an intramolecular dicarbofunctionalization of a modular alkyne. The approach addresses selectivity challenges in indenone synthesis and broadens the reaction scope by incorporation of aryl halides. The catalyst is robust and recyclable.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
