Silylium-Catalyzed Activation of DonorAcceptor Strained Rings and Annulation with Indoles

Jérôme Waser, Emma Gabrielle Louise Robert

: Leveraging the unique reactivity profile of donor -acceptor aminocyclopropanes and cyclobutanes allows the preparation of complex nitrogen -substituted molecules. While most reports focus on donor -acceptor strained rings with two geminal carbonyl groups ...

Orientational Self-Sorting in Octahedral Palladium Cages: Scope and Limitations of the “cis Rule”

Kay Severin, Farzaneh Fadaei Tirani, Damien Wen Chen, Jean Charles Edouard de Montmollin, Atena-Bianca Solea

Octahedral coordination cages of the general formula Pd6L1212 were obtained by combining Pd(CH3CN)42 with heteroditopic N-donor ligands. Four different ligands were employed. These ligands have 3-pyridyl donor groups at one end and 4-pyridyl, ...
