  • Dibenzylideneacetone is a component of the catalyst tris ( dibenzylideneacetone ) dipalladium ( 0 ).
  • Dibenzylideneacetone is a component of the catalyst tris ( dibenzylideneacetone ) dipalladium ( 0 ).
  • However, the benzylideneacetone formed via this reaction can undergo another Claisen-Schmidt condensation with another molecule of benzaldehyde to form dibenzylideneacetone.
  • Keto-alkenes are polyhapto ligands that stabilize highly unsaturated low valent metals as found in ( Benzylideneacetone ) iron tricarbonyl and tris ( dibenzylideneacetone ) dipalladium ( 0 ).
  • This catalyzed reaction was also optimized for allyl substrates with catalytic [ Pd 2 ( dba ) 3 ] CHCl 3 and triphenylphosphine ( dba = dibenzylideneacetone ) ( Scheme 13 ).
  • The other major palladium ( 0 ) complex, tris ( dibenzylideneacetone ) dipalladium ( 0 ) ( Pd 2 ( dba ) 3 ), is prepared by reducing sodium tetrachloropalladate in the presence of dibenzylideneacetone.
  • The other major palladium ( 0 ) complex, tris ( dibenzylideneacetone ) dipalladium ( 0 ) ( Pd 2 ( dba ) 3 ), is prepared by reducing sodium tetrachloropalladate in the presence of dibenzylideneacetone.
  • Palladium ( II ) acetate, tetrakis ( triphenylphosphine ) palladium ( 0 ) ( Pd ( PPh 3 ) 4, and tris ( dibenzylideneacetone ) dipalladium ( 0 ) ( Pd 2 ( dba ) 3 ) serve either as catalysts or as starting materials for catalysts.
  • Because relatively weak bases such as NaOH make very little of the enolate ion at equilibrium, there is still a lot of unreacted base left in the reaction mixture, which can go on and remove protons from the alpha carbon of benzylideneacetone, allowing it to undergo another Claisen-Schmidt condensation and make dibenzylideneacetone.
  • The compound undergoes the reactions expected for its collection of functional groups : e . g ., the double bond adds bromine, the heterodiene adds electron-rich alkenes in Diels-Alder reactions to give dihydropyrans, the methyl group undergoes further condensation with benzaldehyde to give dibenzylideneacetone, and the carbonyl forms hydrazones.
