Donor and donor–donor carbenes are two important kinds of carbenes, which have
experienced tremendous growth in the past two decades. This review provides a …

Three-and four-membered rings, widespread motifs in nature and medicinal chemistry, have
fascinated chemists ever since their discovery. However, due to energetic considerations …

Gold carbenes are highly active intermediates in homogeneous gold catalysis, enabling a
large array of transformations such as C–H/X–H insertions, cyclopropanations, and 1, 2 …

Homogeneous gold-catalyzed cyclopropanation has emerged as a powerful method in
organic synthesis due to its rich chemistry and fascinating reactivity. This thriving strategy is …

Metal carbenes usually possess versatile reactivities that are controlled by the presence of
both the metals and the ligands. Diazo compounds are commonly used for the generation of …

Until recently, computational tools were mainly used to explain chemical reactions after
experimental results were obtained. With the rapid development of software and hardware …

Cationic gold complexes in which gold is bound to a formally divalent carbon atom, typically
formulated as gold carbenes or α-metallocarbenium ions, have been widely invoked in a …

By reviewing the recent progress on the elucidation of the structure of gold carbenes and the
definitions of metal carbenes and carbenoids, we recommend to use the term gold carbene …

This review aims to discuss organic semiconductors constructed on dihydroindenofluorene
positional isomers, which are key molecular scaffolds in organic electronics. Bridged …

Cyclopropanation reactions of carbenes with arenes provide a straightforward pathway to
norcaradienes or cycloheptatrienes. This reaction normally requires harsh reaction …
