The [2+ 2] photocycloaddition is undisputedly the most important and most frequently used
photochemical reaction. In this review, it is attempted to cover all recent aspects of [2+ 2] …

Allenes are the simplest class of cumulenes, with two contiguous C C bonds, and show
unique physical and chemical properties. These features make allenes particularly attractive …

Covering: up to the end of 2021 [2+ 2]-Type cyclobutane natural products are
biosynthetically derived from intermolecular [2+ 2] cycloaddition or intramolecular [2+ 2] …

The century old [2+ 2] photocycloaddition reaction appeared as the most synthetically useful
reaction amongst all photochemical reactions. It provides not only cyclobutane ring systems …

Methylene-and alkylidenecyclopropanes (MCPs and ACPs, 1, Figure 1) and-cyclobutanes
