A ligand-controlled rhodium-catalyzed divergent arylation of alkenyl thianthrenium salts with arylboroxines which allows switchable synthesis of both terminal and internal alkene products in a highly selective manner is reported. The use of a diene ligand guides the reaction toward cine-arylation affording terminal alkenes, while the use of a phosphine ligand switches the reaction to ipso-arylation
Herein, we report an efficient photoinduced iron-catalyzed strategy for cross-couplings of alkyl carboxylic and acrylic acids, which provides a powerful tool for the synthesis of a variety of alkenes with polar functional groups. This novel synthetic methodology can also be applied to the preparation of ketones by using α-keto acids. Mechanistic experiments revealed preliminary mechanistic details
