Mild Palladium-Catalyzed Cyanation of (Hetero)aryl Halides and Triflates in Aqueous Media
A mild, efficient, and low-temperature palladium-catalyzed cyanation of (hetero)aryl halides and triflates is reported. Previous palladium-catalyzed cyanations of (hetero)aryl halides have required higher temperatures to achieve good catalytic activity. This current reaction allows the cyanation of a general scope of (hetero)aryl halides and triflates at 2-5 mol % catalyst loadings with tempera...
متن کاملAryl-aryl bond formation by transition-metal-catalyzed direct arylation.
The biaryl structural motif is a predominant feature in many pharmaceutically relevant and biologically active compounds. As a result, for over a century1 organic chemists have sought to develop new and more efficient aryl-aryl bond-forming methods. Although there exist a variety of routes for the construction of aryl-aryl bonds, arguably the most common method is through the use of transition-...
متن کاملTransition metal catalyzed synthesis of aryl sulfides.
The presence of aryl sulfides in biologically active compounds has resulted in the development of new methods to form carbon-sulfur bonds. The synthesis of aryl sulfides via metal catalysis has significantly increased in recent years. Historically, thiolates and sulfides have been thought to plague catalyst activity in the presence of transition metals. Indeed, strong coordination of thiolates ...
متن کاملPd-Catalyzed Nucleophilic Fluorination of Aryl Bromides
On the basis of mechanism-driven reaction design, a Pd-catalyzed nucleophilic fluorination of aryl bromides and iodides has been developed. The method exhibits a broad substrate scope, especially with respect to nitrogen-containing heteroaryl bromides, and proceeds with minimal formation of the corresponding reduction products. A facilitated ligand modification process was shown to be critical ...
متن کاملPractical iron-catalyzed dehalogenation of aryl halides.
An operationally simple iron-catalyzed hydrodehalogenation of aryl halides has been developed with 1 mol% Fe(acac)(3) and commercial t-BuMgCl as reductant. The mild reaction conditions (THF, 0 degrees C, 1.5 h) effect rapid chemoselective dehalogenation of (hetero)aryl halides (I, Br, Cl) and tolerate F, Cl, OR, SR, CN, CO(2)R, and vinyl groups.
