A Comparative Study of Dibenzylideneacetone Palladium Complexes in Catalysis
Commercial 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 quantitative and could not be predicted reliably on the basis of any physical 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.
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Formula: C17H14O. I hope my blog about 538-58-9 is helpful to your research.
