Prof. Dr. Harder
Sjoerd Harder, born in the Netherlands, obtained his Ph.D. degree in experimental organolithium chemistry under the supervision of Lambert Brandsma (1990, Utrecht) for which he was awarded the H.J. Backer prize in organic chemistry (Royal Dutch Chemistry Association – KNCV). After post-doctoral stays with Paul von R. Schleyer (Erlangen), Andrew Streitwieser (Berkeley) and Hans Brintzinger (Konstanz), he did his Habilitation in Inorganic and Organometallic Chemistry and started an academic research career.

Product formation is controlled by the Mg/Ba ratio and temperature. Crystal structures are described. While 3 is fully insoluble, clusters 1 and 2 retain their structures in aromatic solvents. DFT calculations and AIM analyses indicate highly ionic bonding with Mg−H and Ba−H bond paths. Also unusual H−⋅⋅⋅H− bond paths are observed. Catalytic hydrogenation with MgN“2, BaN”2 and the mixture...
New horizons in low oxidation state group 2 metal chemistry Publikation 202 als PDF laden (5.722 KB)By: Roesch, Bastian; Harder, Sjoerd Chemical Communications (Camebridge, United Kingdom) (2021), 57(74), 9354-9365 Language: English, Database: CAplus and MEDLINE A review. Since the seminal report on Mg in the +1 oxidation state in 2007, low-valent complexes featuring a MgI-MgI bond developed from trophy mols. to state-of-the-art reducing agents. Despite increasing interest in low-valency of the other group 2 metals...
Carbon-Halogen Bond Activation with Powerful Heavy Alkaline Earth Metal Hydrides Publikation 201 als PDF laden (2.598 KB)Carbon-Halogen Bond Activation with Powerful Heavy Alkaline Earth Metal Hydrides Publikation 201 als PDF laden (2.598 KB) [/four_columns_three_last] By: Wiesinger, Michael; Rosch, Bastian; Knuepfer, Christian; Mai, Jonathan; Langer, Jens; Harder, Sjoerd European Journal of Inorganic Chemistry (2021), 2021(36), 3731-3741 | Language: English, Database: CAplus Reaction of [(DipePBDI)SrH]2 with C6H5X (X = Cl, Br, I) led to hydride-halogenide exchange (DipePBDI = HC[(Me)CN-2,6-(3-pentyl)phenyl]2). Conversion rates increase with increasing halogen size (F < Cl < Br < I). Reaction of [(DipePBDI)SrH]2 with C6H5F was slow and ill-defined but addition of C6H4F2 gave smooth hydride-fluoride exchange. After addition of THF the full range of Sr halogenides was structurally characterized: [(DipePBDI)SrX·THF]2 (X = F, Cl, Br, I)...
