coupling partner. These polyaromatic structures are obtained in high yields, in 10 min at room temperature, with minimal waste generation (E‐factors as low as 1.5) and without the need for strict inert conditions, making this process highly efficient and practical in comparison to classical methods. As illustration, several key intermediates of widely used BINOL‐derived structures are readily prepared

First facile and efficient oxidativecouplingreaction of alkylarenes leading to alkylbiaryls using a combination of hypervalentiodine(III) reagent, phenyliodine(III) bis(trifluoroacetate) (PIFA), and BF3·Et2O has been developed.
N-Heterocyclic Carbene-Pd Polymers as Reusable Precatalysts for Cyanation and Ullmann Homocoupling of Aryl Halides: The Role of Solvent in Product Distribution
N‐heterocyclic carbene (NHC) polymer with N‐dodecyl‐substituted groups was found to be a highly efficient precatalyst for cyanation of various aryl halides by using nontoxic cyanic source [K4Fe(CN)6] under relatively mild reaction conditions. Several aryliodides, bromides, and activated chlorides were successfully converted to their corresponding benzonitrile derivatives without using additives (such as reducing
