Book Description
Chapter 1. Palladium-Catalyzed Fluorination of Cyclic Vinyl Triflates: Dramatic Effect of TESCF3 as an Additive A method for the synthesis of cyclic vinyl fluorides with high levels of regiochemical fidelity has been achieved by Pd-catalysis employing a new biarylphosphine ligand and TESCF3 as a crucial additive. Five, six, and seven-membered vinyl triflate substrates, as well as a few acyclic substrates undergo the transformation successfully. The intriguing "TESCF3 effect" provided a new tool for addressing the problem of the formation of regioisomers in Pd-catalyzed fluorination reactions. Chapter 2. Mechanistic Studies on Pd-Catalyzed Fluorination of Cyclic Vinyl Triflates: Evidence for in situ Ligand Modification by TESC3 as an additive. A detailed mechanistic hypothesis for the Pd-catalyzed fluorination of cyclic vinyl triflates, and the unusual effect of TESCF3 as an additive has been developed by combined experimental and computational studies. The preference of conducting [beta]-hydrogen elimination rather than reductive elimination from the trans-LPd(vinyl)F complex, which is generated predominantly due to the trans-effect, caused the poor regioselectivity of the fluorination reaction under TESCF3-free conditions. An in situ ligand modification by trifluoromethyl anion, leading to the generation of the cis-LPd(vinyl)F complex which prefers reductive elimination rather than Phydrogen elimination, is proposed to be responsible for the improved regioselectivity of the fluorination reaction when TESCF3 was used as an additive. Chapter 3. CuH-Catalyzed Enantioselective Alkylation of Indoles with Ligand-Controlled Regiodivergence A method for the enantioselective synthesis of either NI- and C3-chiral indoles by CuH-catalysis, depending on the choice of ligand, was developed. In contrast to conventional indole functionalization in which indoles are used as nucleophiles, hydroxyindole derivatives are employed as electrophiles in this method. DFT calculations indicated that the extent to which the Cu-P bonds of the alkylcopper intermediate distort, determines the regioselectivity of the reaction.

Book Description
Filling a gap in the literature, this book comprehensively reviews catalytic C-H addition reactions of (hetero)aromatic hydrocarbons across carbon-carbon multiple bonds. In so doing, it summarizes both the scope as well as the limitations of different catalyst systems and building blocks, while highlighting their application to the synthesis of pharmaceuticals as well as commodity chemicals. Focusing on the latest developments, the team of authors comprising leaders in the field covers such topics as the hydroarylation of olefins, alkyne hydroarylation in the presence of transition metal catalysts, reaction of alkynes with arylboronic acids, and allene hydroarylation, as well as the synthesis of functionalized arenes and heteroaromatics. A must-have for synthetic chemists in academia and industry dealing with catalysis, organometallic chemistry, the synthesis of natural products, fine chemicals, pharmaceuticals, products of the chemical industry and organic materials.
