Description

MilliporeSigma Sigma Organics products encompass a wide range of quality reagents, solvents, catalysts, and building blocks for organic synthesis. From benchtop discovery to process development and scale-up, Sigma Organics solutions are built to meet the needs of synthetic chemists.

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.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.
