Summary: A new method for the differential dihydrofunctionalization of terminal alkynes has been developed, enabling the synthesis of allylic boronate esters through a reductive three-component coupling reaction. This transformation, promoted by a copper/palladium catalyst system, hydrofunctionalizes both pi-bonds of the alkyne. The method is compatible with a wide range of functional groups.

Summary: The copper-free Heck-Cassar-Sonogashira (HCS) reaction is a powerful method for C-C bond formation in organic synthesis and has several industrial applications. This study investigated the mechanism of the copper-free HCS reaction by conducting stoichiometric and catalytic reactions and analyzing the role of the base. The results showed that the base can accelerate the reduction of the precatalyst and decrease the energy barrier for the alkyne carbopalladation step.

Summary: In this work, a novel fluorescence active benzotriazole-coumarin derivative, BTANC, was synthesized as a ligand in Pd(II) cation coordination. It was found that Pd(II) effectively quenched the fluorescence of BTANC, indicating the potential of using fluorescence signal to monitor the completion of the Sonogashira coupling reaction.

Summary: A bimetallic Pd/Cu catalyst supported on a metal-organic-framework-derived cobalt oxide was prepared and characterized. The catalyst showed high activity in promoting the Sonogashira reaction of aryl iodides with terminal alkynes at low loading. However, its catalytic activity slightly decreased after being recovered and reused.

Summary: Suzuki-Miyaura cross-coupling reaction is a powerful method to construct carbon-carbon bonds and is widely used in the synthesis of functional organic compounds. In this study, zeolite-encased Pd particles (Pd@MFI) were successfully prepared and investigated as promising heterogeneous catalysts for the Suzuki-Miyaura cross-coupling reaction. The Pd@MFI catalysts showed high activity, with dispersed Pd particles efficiently stabilized within the MFI zeolite matrix. The presence of basic sites adjacent to Pd sites was crucial for achieving high catalytic activity.

Summary: Catalytic Sonogashira cross-coupling reactions are efficient and versatile for constructing complex alkynes from readily available starting materials. However, the development of transition-metal-catalyzed Sonogashira cross-coupling reactions of alkyl electrophiles is still limited. Current research focuses on the application of palladium, nickel, and copper catalysts, as well as achieving asymmetric Sonogashira cross-coupling reactions.

Summary: The product obtained by the reaction of deprotonation of 2-mercaptobenzothiazole or methimazole with copper iodide in the presence of tertiary phosphines showed high catalytic activity in coupling reactions. The investigation into the nature of active species emphasized the crucial role of organosulfur and organophosphorus compounds. The coupling reactions were successfully carried out at low catalyst loadings in water/THF with relatively short reaction times.

Summary: Type II photoelimination reactions are crucial in biological systems, and nitro substituents have unusual effects in aryl ketones. The low quantum yield for the formation of nitro substituent may be due to rapid deactivation of the carbonyl localized state. Research on these reactions is important in understanding their mechanisms and effects.
