Abstract The concept of 1, 3‐dipolar cycloadditions was presented by Rolf Huisgen 60 years
ago. Previously unknown reactive intermediates, for example azomethine ylides, were …

This review highlights key reactivities relying on C–C bond cleavages of cyclopropenes.
Metal-catalyzed and metal-free transformations are covered in reactions involving direct ring …

This Review describes the development of strategies for carbonyl–olefin metathesis
reactions relying on stepwise, stoichiometric, or catalytic approaches. A comprehensive …

Carbonyls and alkenes are versatile functional groups, whose reactivities are cornerstones
of organic synthesis. The selective combination of two carbonyls to form an alkene—a …

The beauty of one‐pot cascade reaction lies in the efficient disconnection and construction
of several bonds in a single reaction flask, without the isolation of any intermediates. Herein …

The olefin metathesis reaction of two unsaturated substrates is one of the most powerful
carbon–carbon-bond-forming reactions in organic chemistry. Specifically, the catalytic olefin …

Transfer hydrogenation, alkene metathesis, and alkyne metathesis possess great value to
the synthetic chemistry community. One of the key features of these processes is their …

Polycyclic aromatic hydrocarbons are important structural motifs in organic chemistry,
pharmaceutical chemistry, and materials science. The development of a new synthetic …

The olefin–olefin metathesis reaction has emerged as one of the most important carbon–
carbon bond-forming reactions, as illustrated by its wide use in the synthesis of complex …

As one type of chromene, 2H-chromenes represent important oxygen heterocycles, which
not only widely exist in natural products, pharmaceutical agents and biologically relevant …
