Publikováno v: Laursen, S, Jensen, M T, Lindhardt, A T, Jacobsen, M F & Skrydstrup, T 2016, ' A Palladium-Catalyzed Double Carbonylation Approach to Isatins from 2-Iodoanilines ', European Journal of Organic Chemistry, vol. 2016, no. 10, pp. 1881-1885 . https://doi.org/10.1002/ejoc.201600143

A high-yielding procedure for the synthesis of isatins has been developed. Sequential Pd-catalyzed double carbonylation of 2-iodoanilines with near stoichiometric amounts of CO followed by acid-promoted cyclization readily affords an array of isatins

Publikováno v: Tan, Q, Zhang, C, Wang, N, Zhu, X, Sun, Q, Jacobsen, M F, Gothelf, K V, Besenbacher, F, Hu, A & Xu, W 2014, ' Tailoring on-surface supramolecular architectures based on adenine directed self-assembly ', Chemical Communications, vol. 50, no. 3, pp. 356-358 . https://doi.org/10.1039/C3CC46149A

From an interplay of high-resolution scanning tunneling microscopy (STM) imaging and density functional theory (DFT) calculations we demonstrate that by delicately choosing the parent molecule (adenine) we are able to tune the self-assembled nanostru
