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+ …

We report a method for the crossed [2+ 2] cycloaddition of styrenes using visible light
photocatalysis. Few methods for the synthesis of unsymmetrically substituted cyclobutanes …

The synthesis of four membered heterocycles usually requires multi‐step procedures and
prefunctionalized reactants. A straightforward alternative is the photochemical [2+ 2] …

Efficient [2+ 2] heterodimerizations of dissimilar acyclic enones can be accomplished upon
visible light irradiation in the presence of a ruthenium (II) photocatalyst. Similar …

When aiming to synthesize molecules with elevated molecular complexity starting from
relatively simple starting materials, photochemical transformations represent an open …

We report that Ru (bipy) 3Cl2 can serve as a visible light photocatalyst for [2+ 2] enone
cycloadditions. A variety of aryl enones participate readily in the reaction, and the …

Solar energy is clean, abundant, and more importantly, renewable. As such, any reaction
that efficiently harvests and converts solar energy into chemical energy is more important …

Photochemical reactions are remarkable for their ability to easily assemble cyclobutanes
and other strained ring systems that are difficult to construct using other conventional …

Abstract UV-activated alkyne–alkene [2+ 2] cycloaddition has served as an important tool to
access cyclobutenes. Although broadly adopted, the limitations with UV light as an energy …

We report on the use of visible light to conduct carbene-transfer reactions of donor/acceptor
diazoalkanes with cyclooctatetraene and polyunsaturated carbocycles to give the …
