ionic additive systems biphasic catalysis reaction

摘要

A biphasic reaction system, said system having (i) an aqueous phase containing a catalyst, and (ii) an organic phase containing a substrate and product, and in which the reaction is for alkene hydrogenation, hydrosilation of alkenes , hydroboration of alkenes, hydrovinylation alkene hydroformylation of alkenes, oxidation of alkenes, hydroxycarbonylation of alkenes, or a coupling reaction Heck, Suzuki, Stille or Sonigashira; characterized in that the aqueous phase also contains an additive, and the additive is an ionic molecule consisting of an organic cation with an anion, wherein the organic cation having the formula: ** ** Formula in which R4 is a C7-9 linear or branched chain alkyl; and wherein the anion is a halide.
