Disclosed herein are methods in which colloidal quantum dots (QDs) can serve as visible-light chromophores, photocatalysts, and reusable scaffolds for homo- and hetero-intermolecular [2+2] photocycloadditions. The methods may lead to >90% tunable regioselectivity and up to 98% diastereoselectivity for previously minor syn-cyclobutane products, including the syn-head-to-tail cyclobutane.

The present invention relates to a method for producing an ?-aryl substituted carbonyl compound (e.g., an ?-aryl substituted cyclic ketone) from a carbonyl compound (e.g., a cyclic ketone) using an aryl halide or a heteroaryl halide and a photocatalyst (e.g., acridinium, helicenium, angulenium, or a combination thereof) in the presence of an amine compound. The method of the present invention is particularly useful in producing an ?-aryl substituted carbonyl compound (e.g., an ?-aryl substituted cyclic ketone) from an unactivated carbonyl compound (e.g., an unactivated cyclic ketone).
