Latest Patents

Andreas Leitner holds a patent for "Iron catalyzed cross coupling reactions of aromatic compounds." This process involves the production of compounds Ar—R through a cross-coupling reaction of an organometallic reagent R-M with an aromatic or heteroaromatic substrate Ar—X. The reaction is catalyzed by one or several iron salts or iron complexes, which can be present homogeneously or heterogeneously in the reaction mixture. This invention is particularly noteworthy as it replaces expensive and toxic noble metal catalysts with affordable and benign iron salts or complexes. The process allows for the use of commercially attractive aryl chlorides and various aryl sulfonates as starting materials, can be performed under 'ligand-free' conditions, and typically results in short reaction times.
