Investigations into Transition-Metal-Catalyzed Arene Trifluoromethylation Reactions Transition-Metal-Catalyzed Arene Trifluoromethylation Reactions
Trifluoromethyl-substituted arenes and heteroarenes are widely prevalent in pharmaceuticals and agrochemicals. As a result, the development of practical methods for the formation of aryl–CF3 bonds has become an active field of research. Over the past five years, transition-metal-catalyzed cross-coupling between aryl–X (X = halide, organometallic, or H) and various ‘CF3’ reagents has emerged as ...
متن کاملTransition Metal-Catalyzed Decarboxylative Coupling Reactions of Alkynyl Carboxylic Acids
The decarboxylative couplings of alkynyl carboxylic acids are an attractive area of research in organic chemistry, because the structure of aryl alkyne is one of the important building blocks for the synthesis of p-conjugated compounds. The use of alkynyl carboxylic acid as an alkyne source has several advantages in handling and storage. As a catalyst, palladium, copper, nickel, and silver were...
متن کاملTransition metal-catalyzed allylic substitution reactions with unactivated allylic substrates.
The transition metal-catalyzed allylic substitution of unactivated allylic substrates (allylic alcohols, allylic ethers and allylic amines) is rapidly becoming an important area of research. There are several advantages to using these substrates in allylic substitution reactions: the use of unactivated alcohols minimizes the production of waste by-products and reaction steps; and allylic ethers...

متن کاملMetal-Catalyzed Hydrocarbon Conversion Reactions†
Palladium-catalyzed acetylene trimerization and the metathesis of olefins catalyzed by molybdenum and its oxides are investigated in ultrahigh vacuum and at high pressures. Benzene is formed on Pd(111) by the reaction between adsorbed acetylene and a surface C4 metallocycle. The resulting benzene evolves in temperature-programmed desorption in two distinct states. The low-temperature state is p...
