Tris(dibenzylideneacetone)dipalladium(0) or [Pd 2 (dba) 3] is an organopalladium compound.The compound is a complex of palladium(0) with dibenzylideneacetone (dba). It is a dark-purple/brown solid, which is modestly soluble in organic solvents.
Dibenzyl ketone, or 1,3-diphenylacetone, is an organic compound composed of two benzyl groups attached to a central carbonyl group. This results in the central carbonyl carbon atom being electrophilic and the two adjacent carbon atoms slightly nucleophilic.
Benzylideneacetone can be efficiently prepared by the base-induced condensation of acetone and benzaldehyde: [3]. CH 3 C(O)CH 3 + C 6 H 5 CHO → C 6 H 5 CH=CHC(O)CH 3 + H 2 O. However, the benzylideneacetone formed via this reaction can undergo another Claisen-Schmidt condensation with another molecule of benzaldehyde to form dibenzylideneacetone.
Benzylacetone (IUPAC name: 4-phenylbutan-2-one) is a liquid with a sweet, flowery smell that is considered to be the most abundant attractant compound in flowers (e.g. Coyote Tobacco, Nicotiana attenuata) [1] [2] and one of volatile components of cocoa.
