The first example of selective Pd-catalyzed mono-α-arylation of acetone employing aryl chlorides, bromides, iodides, and tosylates is reported. The use of appropriately designed P,N-ligands proved to be the key to controlling the reactivity and selectivity. The reaction affords good yields with substrates containing a range of functional groups at modest Pd loadings using Cs2CO3 as the base and employing acetone as both a reagent and the solvent. The experimental process involved the reaction of 4-Chloro-2-fluorotoluene(cas: 452-75-5).Recommanded Product: 4-Chloro-2-fluorotoluene

On March 16, 2018, Yang, Shuai; Wang, Feng; Wu, Yanqi; Hua, Wenkai; Zhang, Fengzhi published an article.Synthetic Route of 99-60-5 The title of the article was Synthesis of Functionalized Triphenylenes via a Traceless Directing Group Strategy. And the article contained the following:

A ligand-free Pd-catalyzed cascade reaction between o-chlorobenzoic acids and cyclic diaryliodonium salts is reported. This one-pot procedure involves a carboxylic acid directed O-arylation followed by intramol. decarboxylative annulation affording various valuable triphenylenes, e.g., I, which can be further transformed into diversified building blocks for material chem. It was shown that an aromatic halide can react with diaryliodonium salts under the direction of carboxylic acid functionality. It was also demonstrated that the carboxylic acid could be employed as both a traceless directing group and functional handle for the atom- and step-economical one-pot double cross-coupling annulation reaction with cyclic diaryliodonium salts as the π-extending agents. The experimental process involved the reaction of 2-Chloro-4-nitrobenzoic acid(cas: 99-60-5).Synthetic Route of 99-60-5
