摘要： An organic reductant, in particular an organo silicon reductant suitable for activating supported catalysts of the type MOnEm, wherein E is S and/or Se, in particular MOn, wherein M is W, Mo or Re, is described as well as its use in metathesis reactions. The reduced catalysts are able to metathesize olefins at low temperatures and are therefore also suitable for metathesis of functionalized olefins.

摘要： A method for converting an N,N-dialkylamide compound into an ester compound includes using a fourth period transition metal complex as a catalyst. The fourth period transition metal complex is obtained by a reaction of a precursor having a fourth period transition metal with a nitrogen-containing compound or a phosphorus-containing compound.
