Efficient Catalytic Insertion of Acetylenes into a Carbon-Carbon Single Bond of Nonstrained Cyclic Compounds under Mild Conditions

摘要

Chemical transformations starting from the dissociation of carbon-carbon bonds are important and highly efficient methods to synthesize useful organic compounds because the transformations can change the skeletons of organic compounds directly.However,it is generally difficult to carry out the transformations under mild reaction conditions because carbon-carbon bonds are very strong and are usually covered with carbon-hydrogen or other bonds.
