In 2019,Organic Process Research & Development included an article by Weber, Philip; Biafora, Agostino; Doppiu, Angelino; Bongard, Hans-Josef; Kelm, Harald; Goossen, Lukas J.. HPLC of Formula: 51364-51-3. The article was titled 《A Comparative Study of Dibenzylideneacetone Palladium Complexes in Catalysis》. The information in the text is summarized as follows:
Com. Pdx(dba)y from various suppliers was found to vary considerably in appearance, homogeneity, purity, and catalytic activity. The Buchwald-Hartwig amination of 4-bromoanisole (5) with aniline (6) was established as a sensitive test reaction to probe the efficiency of Pdx(dba)y batches in catalytic transformations. The yields obtained with 17 different Pdx(dba)y batches ranged from 10% to nearly quant. and could not be predicted reliably on the basis of any phys. or spectroscopic descriptor alone. The best results in the catalytic test reaction were consistently achieved with a self-made slowly crystallized Pd2(dba)3·toluene adduct. A protocol is disclosed that allows batches of Pdx(dba)y with unsatisfactory or inconsistent performance to be converted into this reliable precatalyst. After reading the article, we found that the author used Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3HPLC of Formula: 51364-51-3)
Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3) is the most widely used PdO precursor complex in synthesis and catalysis, in particular as a catalyst for various coupling reactions. HPLC of Formula: 51364-51-3 It is used as a catalyst precursor for palladium-catalyzed carbon-nitrogen bond formation, conversion of aryl chlorides, triflates and nonaflates to nitroaromatics.
