Heckreactions of polymer bound aryl iodide (1) or styrene (2) with olefins or aryl halides generally gave good yields of products of high purity. The methodology developed can be applied as a convenient procedure for generating 1,2-disubstituted olefins in combinatorial chemical libraries.
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.
