Since firstly discovered in 1964,[1] Fischer carbene complexes have been developed into valuable and powerful organometallic reagents for organic synthesis.
Recently much attention has been paid to a novel redox-neutral strategy using an oxidizing directing group(internal oxidant) in C-H activation reactions.
Catalysis is one of the important approaches to green chemistry.In recent years,the metal nanoparticles are introduced into the field of organic synthesis as catalysts,because of its large surface-to-
Nearly ten years,homogeneous asymmetric catalysis of gold has gotten a rapid development.However,gold and chiral ligands are too expensive to apply industry.
N-allenamides,a particularly accessible type of allenic scaffold,has emerged as a versatile and powerful building block in variety of synthetic transformation.
