Solvent Free Green Synthesis f 4-Substituted Thiocarbamido- Naphthols
Bibliographic record
Abstract
Recently in this laboratory we developed new solvent free green synthetic methods for the synthesis of 4-phenylthiocarbamido-1-naphthol, 4-(p-chloro)phenylthiocarbamido-1-naphthol, 4-(o-methyl)phenylthiocarbamido-1-naphthol, 4-(p-methyl)phenylthiocarbamido-1-naphthol, and 4-(m-methyl)phenylthiocarbamido-1-naphthol by interacting 4-amino-1-naphthol with p-chlorophenylisothiocynate, p-tolylisothiocynate, o-tolylisothiocynate and m-tolylisothiocynate in presence of sweet lemon juice, lemon and orange juice respectively which are hither to unknown. Yet such attempts were not carried out by any researcher for 4-amino-1-naphthol. Previous researchers carried out such type of synthesis for different molecules in organic solvents as medium, which are hazardous and make pollution of environment. Newly synthesized substituted thiocarbamidonapthols was characterized by elemental analysis, chemical characteristics and spectral studies.

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.
