Abstract The photochemical [2+ 2] cycloaddition of styrenes provides a frequently used route
for the synthesis of multi-substituted cyclobutanes. Despite the extensive studies in noble …

Abstract 2+ 2 Photocycloadditions are idealized, convergent construction approaches of 4-
membered heterocyclic rings, including azetidines. However, methods of direct excitation …

Abstract Light-induced [2+ 2] cycloaddition is the most straightforward way to generate
cyclobutanes, which are core structures of many natural products, drugs and bioactive …

Photocycloadditions are often typified by the oxetane-forming Paternò–Büchi reaction.
However, the mechanistic constraints of carbonyl excitation and olefin interception have …

Photocycloadditions of 1, 3‐dienes represent a powerful yet synthetically underutilized class
of reactions. We report that visible light absorbing transition metal complexes enable the [2+ …

Photocatalytic [2+ 2] cycloaddition is a useful tool for the synthesis of cyclobutane
derivatives, which contributes a large part to natural compound production. Usually, the [2+ …

Photo [2+ 2] cycloaddition of olefins is a sought-after tool for making cyclobutanes, which are
the building blocks for a wide range of biologically active molecules and natural products …

Abstract Photocatalytic oxidative [3+ 2] cycloaddition of phenol-olefin is an economy and
green strategy to synthesize 2, 3-Dihydrobenzofurans (2, 3-DHBs) compared with the …

The ability to exert spatial and temporal control over a transition-metal catalyst offers diverse
opportunities for the fabrication of functional materials. Using an external stimulus such as …

Polypyridyl metal complexes of ruthenium (II) have emerged as efficient single electron
transfer (SET) reagents for photocatalytic reactions, allowing a variety of organic …
