Synthesis

Our synthetic laboratory is well equipped for organic and organometallic syntheses. We handle and prepare highly air sensitive compounds by Schlenk/vacuum line- and glove box techniques. Our syntheses are mostly focused on organometallic compounds to be applied in molecular electronics. Mostly we prepare our compounds using well-documented methods, but occasionally we develop new procedures. In the course of our study we developed a synthetic strategy to obtain both iodoferrocene and 1,1’-diiodoferrocene in excellent yields and high-purity (see Dalton Trans., 2014, 43, 11815-11818). Recently, we also described a synthetic protocol to efficiently prepare various 1′-functionalized iodoferrocenes and their use in Pd-catalyzed Heck coupling reactions (see Eur. J. Inorg. Chem. 20162016 (9), 1314-1318).
