And the article was published in Angewandte Chemie, International Edition in 2019. Computed Properties of C51H42O3Pd2 The author mentioned the following in the article:
Ylide-functionalized phosphine ligands (YPhos) were rationally designed to fit the requirements of Buchwald-Hartwig aminations at room temperature This ligand class combines a strong electron-donating ability comparable to NHC ligands with high steric demand similar to biaryl phosphines. The active Pd species are stabilized by agostic C-H…Pd rather than by Pd-arene interactions. The practical advantage of YPhos ligands arises from their easy and scalable synthesis from widely available, inexpensive starting materials. Benchmark studies showed that YPhos-Pd complexes are superior to the best-known phosphine ligands in room-temperature aminations of aryl chlorides. The utility of the catalysts was demonstrated by the synthesis of various arylamines in high yields within short reaction times. In addition to this study using Tris(dibenzylideneacetone)dipalladium(0), there are many other studies that have used Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Computed Properties of C51H42O3Pd2) was used in this study.
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.
