Abstract
[12131-44-1 C18H18Cl2Pd2 (MW 518.08) InChI = 1S/2C9H10.2ClH.2Pd/c2*1-2-6-9-7-4-3-5-8-9;;;;/h2*2-8H,1H3;2*1H;;/q;;;;2*+1/p-2/b2*6-2+;;;; InChIKey = KETGKEIOEMLQGE-LVDNZMOCSA-L (palladium(II) complex used for allylation and CH carbonylation) Synonyms: bis[cinnamyl palladium(II) chloride], palladium(1-phenylallyl)chloride dimer, [(cinnamyl)PdCl]2, [Pd(1-phenylallyl)Cl]2. Physical Data: 1H NMR (DMSO-d6): δ 7.0–7.8 (m, 5H), 6.40 (dt, 1H, J = 12, 10 Hz), 5.13 (d, 1H, J = 12 Hz), 3.83 (d, 2H, J = 10 Hz) ppm;1 mp 218–220 °C. Form Supplied in: yellow powder, commercially available. Preparation: prepared by adding a solution of cinnamyl chloride in ethanol to a solution of palladium chloride and lithium chloride in hot water. Upon bubbling carbon monoxide for 15 min at room temperature, an orange solid forms, which is stirred for 1 day at room temperature and for 1 day at 0 °C. Then, the precipitate is collected by filtration, and washed with methanol and ether.1 Purification: recrystallization from chloroform/diethyl ether.1 Handling, Storage, and Precautions: stable under regular storage conditions; air stable.
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.
