A tandem Pd2(dba)3 participated C-C bond cleavage of O-bromophenyl cyclobutanone derivatives/Michael addition reaction sequence was realized. We disclosed the first intramol. C-Br bond triggered ring opening reaction of arylcyclobutanones, distinct from related reports in which the reactions were initiated by arylboron, silane or unsaturated chem. motifs, among others. The in situ generated palladium species underwent ring expansion process leading to methyleneindanones, which further reacted with dba to provide benzospirones in one step. In the experiment, the researchers used Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Computed Properties of C51H42O3Pd2)
Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3) is used in the preparation of semiconducting polymers processed from nonchlorinated solvents into high performance thin film transistors.Computed Properties of C51H42O3Pd2It is used as catalyst for the synthesis of epoxides, alpha-arylation of ketones, in combination with BINAP for the asymmetric heck arylation of olefins, site-selective benzylic sp3 palladium-catalyzed direct arylation and homoallylic diamination of terminal olefins.
