摘要:
Nature is capable of storing solar energy in chemical bonds via photosynthesis through a series of C—C, C—O and C—N bond-forming reactions starting from CO2 and light. Direct capture of solar energy for organic synthesis is a promising approach. Lead (Pb)-halide perovskite solar cells reach 24.2% power conversion efficiency, rendering perovskite a unique type material for solar energy capture. We show that photophysical properties of perovskites is useful in photoredox organic synthesis. Because the key aspects of these two applications are both relying on charge separation and transfer. Here we demonstrated that perovskites nanocrystals are exceptional candidates as photocatalysts for fundamental organic reactions, i.e. C—C, C—N and C—O bond-formations. Stability of CsPbBr3 in organic solvents and ease-of-tuning their bandedges garner perovskite a wider scope of organic substrate activations.

摘要:
A class of mono-protected 3-amino-2-hydroxypyridine (MPAHP) ligands that enable the meta-C—H arylation of anilines, phenols, phenylacetic acids, and biologically relevant heterocyclic compounds using norbornene as a transient mediator is disclosed, such as in the formation of a reaction product of Formula IA: The applicability of this meta-arylation methodology in the pharmaceutical industry is illustrated for heteroaryl substrates and heteroaryl iodide coupling partners, a feat made possible by using the MPAHP ligand. The enabling nature of MPAHP ligands to achieve other meta-C—H functionalization processes is also illustrated by the development of a meta-C—H amination reaction and a meta-C—H alkynylation reaction.
