Bibliographic record
Abstract
[3375-31-3] C4H6O4Pd (MW 224.52) InChI = 1S/2C2H4O2.Pd/c2*1-2(3)4;/h2*1H3,(H,3,4);/q;;+2/p-2 InChIKey = YJVFFLUZDVXJQI-UHFFFAOYSA-L (trimer) [53189-26-7] InChI = 1S/2C2H4O2.Pd/c2*1-2(3)4;/h2*1H3,(H,3,4);/q;;+2/p-2 InChIKey = YJVFFLUZDVXJQI-UHFFFAOYSA-L (homogenous oxidation catalyst3 that, in the presence of suitable co-reagents, will effect the activation of alkenic and aromatic compounds towards oxidative inter- and intramolecular nucleophilic attack by carbon, heteroatom, and hydride nucleophiles1, 3-5) Alternate Names: bis(acetato)palladium; diacetatopalladium(II); palladium diacetate. Physical Data: mp 205 °C (dec). Solubility: sol organic solvents such as chloroform, methylene chloride, acetone, acetonitrile, diethyl ether. Dissolves with decomposition in aq HCl and aq KI solutions. Insol water and aqueous solutions of NaCl, NaOAc, NaNO3 as well as in alcohols and petroleum ether. Decomposes when heated with alcohols. Form Supplied in: orange-brown crystals; generally available. Preparative Method: preparation of palladium diacetate from palladium sponge was developed by Wilkinson et al.2 Purification: palladium nitrate impurities can be removed by recrystallization from glacial acetic acid in the presence of palladium sponge. Handling, Storage, and Precautions: can be stored in air. Low toxicity.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
