Highly active and selective catalysts of hydrogenation based on palladium bis-acetylacetonate and phenylphosphine

Osmium(III) Acetylacetonate and Its Missing Polymorph: A Magnetic and Structural Investigation

“…Since then, the chemistry of these simple molecules has been heavily explored for a number of applications. , Acetylacetones are chemically simple and tunable ligands, prone to structural modifications by replacing their α-hydrogen atoms or the methyl groups with other fragments. Such chemical flexibility allows the fine-tuning of several properties such as solubility, volatility, color, and melting point of the resultant metal complexes. − At present, they are used as starting materials for the synthesis of nanoparticles, they have a relevant role in polymeric production processes, − and are used as catalysts precursors in many organic syntheses. − The most characterized and studied complexes contain 3d metals, − even though some examples are reported also for the second transition series. , For 5d elements there are only a few examples in the literature. − …”

A Supported Palladium Phosphide Catalyst for the Wacker‐Tsuji‐Oxidation of Styrene

“…[19,20] It is widely known that the presence of isolated metal atoms, as found in homogeneous and single atoms catalysts, results in optimized catalyst performance, especially in terms of selectivity. [6,7,21] Palladium phosphides have been reported as catalysts for hydrogenation, [12,15,16,19,[22][23][24][25] hydrodesulfurizations [10,11,26] and CÀ C coupling reactions, [20] as well as for catalytic water splitting. [27] In all of these cases, the authors have reported the positive effect of phosphorus incorporation into palladium with respect to the catalytic performance.…”

Support Engineering for the Stabilisation of Heterogeneous Pd3P‐Based Catalysts for Heck Coupling Reactions

“…The use of phosphorus in catalysis has greatly been extended from the conventional application as phosphine ligands in homogeneous catalysis [1][2][3] and has now also found significant attention in the field of heterogeneous catalysis. [4][5][6] Hereby, transition metal phosphides have been investigated in detail in various catalytic reactions, [7] such as hydroformylation, [8][9][10] hydrogenation, [11][12][13][14][15][16][17][18][19] photocatalytic Suzuki coupling [20] and desulfurization reactions. [21][22][23] The high catalytic activity of transition metal phosphides can be traced back to the dilution of the transition metal using phosphorus, which leads to the formation of highly uniform and defined "frustrated" single metal sites.…”
