Palladium(II) Acetate

Single-Atom Alloy Formation via Reaction-Driven Catalyst Restructuring

“…The molecular nature of diacetates enables their motion across the network of highly abundant physisorbed H-bonded acetic acid (1757 cm –1 , Figure a) between SiO 2 particles. , Pd and Cu diacetates are known to decompose before melting or vaporizing, , which suggests that a reactive environment is needed to repeatedly reform these species during restructuring. Under these conditions, the mobility would require the solvation of diacetate clusters by acetic acid layers, and some connectivity in these layers across SiO 2 particles would be expected.…”

Aerobic Acyloxylation of Allylic C−H Bonds Initiated by a Pd0 Precatalyst with 4,5‐Diazafluoren‐9‐one as an Ancillary Ligand

“…Efforts to expand the scope of palladium‐catalyzed allylic oxidation to incorporate other carboxylate groups have encountered several limitations. Pd(OAc) 2 is one of the most common commercially available Pd II sources and, therefore, is the most prevalent Pd source for allylic oxidation, among other reactions . Szabó and co‐workers reported two strategies for acyloxylation catalyzed by Pd(OAc) 2 : (a) using 4 equivalents of carboxylic anhydride or (b) incorporating the carboxylate source into their oxidant by utilizing 3–3.5 equivalents of a hypervalent iodine oxidant with the corresponding lithium carboxylate salt .…”
