Hydridic Rhenium Nitrosyl Complexes with Pincer-Type PNP Ligands
Bibliographic record
Abstract
The hydride complexes ReHBr(NO)[HN(C 2 H 4 PR 2 ) 2 ] (R = Pr i, 1a; Bu t, 1b ) were synthesized by reactions of [NEt 4 ] 2 [Re(NO)Br 5 ] with the pincer-type ligands HN(C 2 H 4 PR 2 ) 2 . Treatment of 1a and 1b with Bu t OK led to their dehydrobromination, resulting in the amido hydrides ReH(NO)[N(C 2 H 4 PR 2 ) 2 ] ( 2a, b ), respectively. The dihydride trans -ReH 2 (NO)[HN(C 2 H 4 PPr i 2 ) 2 ] ( 3a ) was obtained by stirring an ether solution of 2a under hydrogen. Similarly, partial conversion of 2b was achieved under hydrogen to give trans -ReH 2 (NO)[HN(C 2 H 4 PBu t 2 ) 2 ] ( 3b ). The structure and properties of complexes 1 − 3 were studied by DFT calculations. Complexes 2a and 3a demonstrated low activity for transfer hydrogenation of acetophenone and cyclohexanone due to instability in 2-propanol.

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.
