일반 설명

Bis(dibenzylideneacetone)palladium(0) (Pd(dba)2) is an air stable Pd0 complex. It is a reagent for the synthesis of allylic substituted cyclopentadienes. It is a homogeneous catalyst. It catalyzes the alkylation of allyl acetates by various nucleophiles under mild conditions.

애플리케이션

Bis(dibenzylideneacetone)palladium(0) (Pd(dba)2) was employed as catalyst in the following studies:
  • Synthesis of isomeric 2-aryl-2,5-dihydrofurans, via Heck coupling of aryl bromides with alkenes using neopentyl phosphine ligands.
  • Heck reaction of benzyl trifluoroacetate and 2,3-dihydrofuran phosphoramidite ligand.
  • Allylation of stabilized anions.
  • Cross coupling of allyl, alkenyl and aryl halides with organostannanes.
  • Cross coupling of vinyl halides with alkenyl zinc species.
  • Carbonylation of alkenyl and aryl halides.
  • Employed with cyclic thiourea ligands in an efficient aerobic oxidation of alcohols to aldehydes and ketones.
