The Binary Ph<sub>2</sub>PCl/GaCl<sub>3</sub> System: A Room‐Temperature Molten Medium for P–P Bond Formation
Bibliographic record
Abstract
Abstract An equimolar reaction mixture of Ph 2 PCl and GaCl 3 at room temperature results in the formation of a melt M consisting of the donor–acceptor complex Ph 2 PCl→GaCl 3 ( 1a ), the chloro(diphenylphosphanyl)diphenylphosphonium cation ( 2a ), and the counteranions [Ga n Cl 3 n +1 ] – ( n = 1, 2, 3). The melt has been characterized by Raman and NMR spectroscopy and is compared with the reaction mixture of Ph 2 PCl and GaCl 3 observed in solution (CH 2 Cl 2 ). The melt provides a facile and reactive source of the diphenylphosphenium cation, as demonstrated with use for P–P bond insertion into (PhP) 5 , to give the 2,3,4,5‐tetraphosphanyl‐1,4‐diphosphonium dication ( 3 ), and reductive coupling with gallium metal to give the diadduct Cl 3 GaPPh 2 PPh 2 GaCl 3 ( 5 ).(© Wiley‐VCH Verlag GmbH & Co.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
