Optimization of the Synthesis of Chloro Dodecachloro Boron Subphthalocyanine.
Bibliographic record
Abstract
During this study, we analyze different methodologies to synthesize previously reported chloro dodecachloro boron subphthalocyanine (Cl-Cl12BsubPc). As we attempt to replicate the previously reported method, we were unable to successfully achieve the yield and purity that was reported, and this negative outcome was confirmed via running many times. This led us to explore different pathways to produce Cl-Cl12BsubPc, for first example, utilizing AlCl3 in axial halide exchange from Br-Cl12BsubPc to Cl-Cl12BsubPc. However, due to inability to track reaction progression during the reaction and only partial conversion, other pathways were considered. Ultimate conclusion was that we were able to synthesize Cl-Cl12BsubPc using BCl3 in p-xylene, where we achieve an improved yield of 69%, with a purity of 93%. Using TGA, to also note, we postulate a reason for the decreased thermal stability of Cl-Cl12BsubPc during train sublimation, and therefore if sublimation was done at higher temperature it results in lower purification yields.

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.
