Application Guide for Palladium Catalyzed Cross-Coupling Reactions

Application

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.

General Description

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.

Synthesis

Bis(dibenzylideneacetone)palladium(0) was prepared by reduction of PdCl2 with methanol in the presence of sodium acetate and dibenzylideneacetone, as dark-violet pre-cipitate with mp 152°C (150°C ).
