Copper-Facilitated Suzuki Reactions: Application to 2-Heterocyclic Boronates
摘要:
The palladium-catalyzed Suzuki-Miyaura reaction has been utilized as one of the most powerful methods for C-C bond formation. However, Suzuki reactions of electron-deficient 2-heterocyclic boronates generally give low conversions and remain challenging. The successful copper(l) facilitated Suzuki coupling of 2-heterocyclic boronates that is broad in scope Is reported. Use of this methodology affords greatly enhanced yields of these notoriously difficult couplings. Furthermore, mechanistic investigations suggest a possible role of copper in the catalytic cycle.

Studying the self-assemblymechanisms and kinetic pathways of IrIII complex monomers has led to their block co-assembly through kinetic control and pathway-switching control, respectively. The well-defined block microstructure has been characterized by TEM and SEM. The present research approach will be an important step forward in the study of the self-assembly of small molecules that can form crystalline
