Main observation and conclusion Pd(OAc) 2 is an extensively utilized palladium source in the palladium initiated transformations either directly or as a catalyst precursor. However, the comprehension of the real structure of Pd(OAc) 2 in solution is still vague. In this work, the structure of palladium acetate in solution was studied in detail by using X‐ray absorption fine structure (XAFS) spectroscopy. The results demonstrate that monomer is the main form for Pd(OAc) 2 in the solution of 1,4‐dioxane, N , N ‐dimethylacetamide (DMA), N , N ‐dimethylformamide (DMF), 1,2‐dimethoxyethane (DME), MeCN and dimethyl sulfoxide (DMSO). In addition, Pd(II) could be reduced to Pd(0) in ethanol solution. The structural information in this research will benefit the understanding of the mechanism of Pd(OAc) 2 involved organic reactions.
