Asymmetrische Katalysen, 71 / Asymmetric Catalyses, 71

The enantioselective hydrosilylation of acetophenone with diphenylsilane in the solvents toluene and CCl 4 was catalysed with a [Rh(COD)Cl] 2 /2-pyridineoxazoline catalyst. The “CCl 4 -effect” (higher enantioselectivity and reactivity) was already confirmed with stoichiometric quantities of CCl 4 with respect to the Rh-catalyst. The influence of other halogenated solvents on the hydrosilylation was investigated.
